8 1 RF100 SNAP Engine OEM Modules RF100 SNAP Engine modules meet IEEE specifications. These modules provide a low-power, highly reliable all-in-one solution to embedded wireless control and monitoring network needs at very low cost. The RF100 SNAP Engine is approved as an FCC Part 15 unlicensed modular transmitter. The modules provide up to 16 channels of operation in the ISM 2.4GHz frequency band. There are two versions of modules. One version has an external power amplifier for extended range. This module will be referred to as an RFET, or RF100 SNAP Engine with external amplifier. The other module has no external power amplifier and is referred to as an RFE, or RF100 SNAP Engine without external amplifier. Figure 1 below consists of block diagrams showing the major subsystems that make up these two versions of RF Engine.

V REFL and V SSAD are connected to the GND pin. 6 Maximum electrical operating range, not valid conversion range. 7 R AS is the real portion of the impedance of the network driving the analog input pin. Values greater than this amount may not fully charge the input circuitry of the ATD resulting in accuracy error. 8 Analog input must be between V REFL and V REFH for valid conversion. Values greater than V REFH will convert to 0x3FF and less. 9 The resolution is the ideal step size or 1LSB = (V REFH V REFL ) / Differential non-linearity is the difference between the current code width (1LSB). The current code width is the difference in the transition voltages to and from the current code. 11 Integral non-linearity is the difference between the transition voltage to the current code and the adjusted ideal transition voltage for the current code. The adjusted ideal transition voltage is (Current Code ½) * (1 / ((V REFH + E FS ) (V REFL + E ZS ))). 12 Zero-scale error is the difference between the transition to the first valid code and the ideal transition to that code. The ideal transition voltage to a given code is (Current Code ½) * (1 / (V REFH V REFL )). Page 12 of 62 SNAP Hardware Technical Manual-v1.3

Here is a partial list of these options. Option Embedded F-Antenna External Antenna Transmit Amplifier Low Noise Amplifier Description With the version of the module with embedded F-antenna, antenna is fully integrated into the module. With the version of the module with the reverse polarity SMA (RPSMA) connector populated, an external antenna can be attached. With the population of an external power amplifier on the transmitter, outdoor line of sight range can be increased from 300 meters to 3000 meters. With the population of an external low noise amplifier on the receiver, receive sensitivity can be improved from -92 dbm to -102 dbm at 1% PER. 13 Full-scale error is the difference between the transition to the last valid code and the ideal transition to that code. The ideal transition voltage to a given code is (Current Code ½) * (1 / (V REFH V REFL )). 14 Input leakage error is error due to input leakage across the real portion of the impedance of the network driving the analog pin. Reducing the impedance of the network reduces the error. 15 Total unadjusted error is the difference between the transition voltage to the current code and the ideal straight-line transfer function. This measure of error includes inherent quantization error (1/2LSB) and circuit error (differential, integral, zero-scale, and full-scale) error. The specified value of E TU assumes zero E IL (no leakage or zero real source impedance). 16 All ACCURACY numbers are based on processor and system being in WAIT state (very little activity and no I/O switching ) and that adequate low-pass filtering is present on analog input pins (filter with 0.01 µf to 0.1µF capacitor between analog input and V REFL ). Failure to observe these guidelines may result in system or microcontroller noise causing accuracy errors which will vary based on board layout and the type and magnitude of the activity.

15 Board Mounting Considerations The RF100 SNAP Engine modules are designed to mount into a receptacle (socket) on the host board. Figure 3 shows an RF100 SNAP Engine module plugged in to a host board. The receptacle sockets are on standard 2mm centers. Suggested receptacles to be used on the host are: (1) Thru-hole receptacle: Samtec MMS L-SV (2) Surface mount receptacle: Samtec MMS L-SV When the module with SMA connector is used, it is recommended that the mounting holes provided in the module on either side of the SMA connector be used with supporting mounting hardware to hard mount the module to either the host board or to the enclosure to handle the mechanical stresses that can occur when an external antenna is screwed into the SMA. Figure 3 shows the RF100 SNAP Engine with SMA connector mounted to the host board. Figure 3 Host Board with RF100 SNAP Engine Mounted and Mounting Hardware For the module with integrated F-antenna, in order to maximize RF range in the direction behind the module, it is recommended that no components or metal (either traces or VCC and GND planes) be on any layers of the host board that lies underneath the module in the area designated by the Keep Out Area shown in the drawings of Figure 2. When using modules of this type (internal antenna) in conjunction with Synapse demonstration boards, it is also recommended that users remove the PCB mounting tab located directly below the F-antenna.

Analog3 is unavailable on RF200 SNAP Engines with a power amplifier. 18 Other SNAP Engines have a debug connection on pin 22. The architecture of the RF200 requires multiple debug connections, which come out on other pins. Rather than leave pin 22 useless, it is available as an additional GPIO or Analog Comparator. This will not be directly accessible on Synapse development boards, but custom circuit designs have the pin available for specialized purposes. Page 22 of 62 SNAP Hardware Technical Manual-v1.3

You can load an RF300 with Si100x firmware and have access to these pins, including SPI functionality, ADC, or interrupts. However you will lose access to the external memory on the RF300, and SPI capabilities on pins 6-8. If you do this, be aware that pulling pin 13 low causes the external memory to be powered, which will result in significantly higher power consumption during sleep. 29 GPIO_16 has limited drive or sink strength, as it routes through a 1 KΩ resistor. The signal from (or to) GPIO_16 can also be read from (or driven into) Engine pin 22, the debug pin, to route around this resistor instead. 30 Note that this is GPIO_0 of the underlying radio hardware, and is unrelated to the GPIO_0 of the SNAP Engine.

39 4 Evaluation Kit SN163 Bridge Demonstration Board The SN163 Bridge provided in the Network Evaluation Kit consists of an Interface Host Board, an RF Engine, and SNAP code loaded in the microcontroller of the RF100 SNAP Engine. The Interface Host Board offers both an RS-232 port and a USB 2.0 port. Either port can be used to interface to a PC. If both ports are plugged in to the PC, only the USB port will be active. A description of the features on the SN163 Bridge follows. Figure 20 shows the top side of the Interface Host Board and identifies the location of the various features to be discussed. Please refer to this picture to locate all features. Figure 20 SN163 Bridge The SN163 Bridge provides a variety of features. These features consist of several options for supplying power, power on/off switch, an LED indicating that external power is being supplied, hardware reset button, RS-232 port, USB 2.0 port, user select button and LED, and a 2 digit seven-segment display. Power to the SN163 Bridge The SN163 Bridge provides three options for supplying power to the electronics. The options are: 1) wall transformer power adapter; 2) USB; and, 3) battery. Also, an LED is provided that lights up whenever an external power source is plugged in. Finally, there is an On/Off switch that controls power to the electronics. SNAP Hardware Technical Manual-v1.3 Page 39 of 62

40 Power Adapter The wall transformer power adapter provided in the kit can be used to provide power. The power adapter generates 9V DC and is plugged in to the power connector. The power supply on the Interface Host Board can accept a wide range of power in to the power connector. It supports a range of both AC and DC input power meeting the following specifications: 1) AC Input power between 6VAC to 24VAC; and, 2) DC Input power between 5VDC to 25VDC. Also, there is protection circuitry if positive and negative are reversed on the plug-in jack to the power connector. The power connector is a 2mm male power jack. The wall transformer mating connector should be a 2.1mm female power plug with polarity as shown in Figure 21. Figure 21 Female Power Plug Polarity USB Power Power can be provided to the SN163 Bridge from the USB port. This happens automatically when the USB cable provided in the kit is plugged into the USB port on the Interface Host Board and into an active USB port on the PC (or a USB power adapter). (NOTE: In order for proper operation of the USB port to occur, USB drivers located in the CD provided in the kit must be loaded on the PC. Please refer to instructions on the Quick Start Guide for loading this driver. Battery Finally, a single AA alkaline battery can be plugged into the battery holder closest to the middle of the Interface Host Board to provide power to the electronics when wall transformer power or USB power is not available. If a battery is plugged in at the same time power is being provided by either the power adapter or USB, then special circuitry on the Interface Host Board will disconnect the battery circuit thereby disabling the battery from providing power. For the SN163 Bridge, the intended operation is to always use the power adapter or the USB bus for power. The battery should be used as a temporary backup to continue to power the SN163 Bridge if AC power is lost. The RS-232 interface circuitry and USB interface circuitry on the Interface Host Board consumes several milliamps of current which will draw down the battery quickly if battery is the only power source. Therefore, there is detection circuitry which will shutdown the on-board RS-232 interface and USB interface if the Interface Host Board is being powered by battery. Also, there is voltage detection circuitry that allows software to distinguish between battery and external power source so that power consumption can be intelligently monitored. For battery operation, the software will detect low battery voltage and provide low battery warning indication. This will be discussed in greater detail in the Synapse Portal Software Users Guide. Page 40 of 62 SNAP Hardware Technical Manual-v1.3

41 NOTICE: It can be seen that two battery holders are present on the Interface Host Board. For the SN163 Bridge, the battery circuitry is configured for single battery operation to be used primarily as a backup power source as discussed above. Only the battery holder nearest the middle of the Interface Host Board is active. If a battery is plugged in to the battery holder on the edge of the board, it provides no power to the Interface Host Board. External Power LED Indicator The external power LED indicator on the Interface Host Board is provided to offer confirmation that the external power source is providing the proper power to the board electronics. This LED will be on if proper external power is coming in to either the power connector or to the USB port. It will not be on if power is being supplied to the board by batteries. Power On/Off Switch There is a power on/off switch provided on the Interface Host Board. This switch controls power to all on-board electronics and RF Engine module except the power supply for external power and external power LED indicator. NOTICE: If external power is coming in from either the power connector or the USB port, the External Power LED Indicator will be ON even if the power switch is OFF. User I/O There are several user I/O capabilities on the SN163 Bridge. These consists of a hardware reset button, a user select button, a user status LED indicator, and a 2-digit seven segment LED display. Reset Button The reset button is used to reset all hardware and re-boot the RF Engine. User Select Button A user button is provided on the SN163 Bridge that can be used for various select functions. This will be discussed in greater detail in the Synapse SNAP Reference Manual. User Status LED Indicator An LED is provided on the SN163 Bridge that can be used for various indicator functions. This will be discussed in greater detail in the Synapse SNAP Reference Manual. 2-Digit Display A 2-digit seven-segment LED display is also provided on the SN163 Bridge that can be used for displaying various sets of data and error indicators. This will be discussed in greater detail in the Synapse SNAP Reference Manual. SNAP Hardware Technical Manual-v1.3 Page 41 of 62

42 External Port Interfaces The SN163 Bridge has two external port interfaces. There is an RS-232 interface and a USB 2.0 interface. RS-232 Interface The SN163 Bridge has a serial RS-232 interface port. This port has a standard female DB-9 style connector. The pin assignments are shown in Table 19 below. DB-9 Pin RS-232 Signal Description Implementation 1 DCD Data-Carrier-Detect Not connected 2 RxD Receive Data Data from RF Engine (to host) 3 TxD Transmit Data Data to RF Engine (from host) 4 DTR Data-Terminal-Ready Connected to DSR 5 GND Ground Ground 6 DSR Data-Set-Ready Connected to DTR 7 RTS Request To Send Request from Host to send data 8 CTS Clear To Send Clear from RF Engine for host to send 9 RI Ring Indicator Not connected Table 19 RS-232 Pin Assignments Setup of this port will be discussed in greater detail in the Synapse Portal Software Users Guide. A standard RS-232 cable for connecting the SN163 Bridge to a PC has been provided in the kit. USB Interface The USB interface on the SN163 Bridge is USB 2.0 compliant. A standard Type-B OEM connector is provided on the USB port of the Interface Host Board. The pin assignments are shown in Table 20 below. Pin Signal Description Implementation 1 VBUS Power Powers the Interface Host Board 2 Data- Transmitted and Received Data (neg) Transmit data to and from the RF Engine 3 Data+ Transmitted and Received Data (pos) Transmit data to and from the RF Engine 4 GND Ground Ground Table 20 USB Pin Assignments Setup of this port will be discussed in greater detail in the Synapse Portal Software Users Guide.

43 5 Evaluation Kit SN111 End Device Demonstration Board The SN111 End Device provided in the Network Evaluation Kit consists of an I/O Host Board, an RF100 SNAP Engine, and SNAP code loaded in the microcontroller of the RF Engine. The I/O Host Board provides an RS-232 port to interface to a PC. A description of the features on the SN111 End Device follows. Figure 22 shows the top side of the I/O Host Board and identifies the location of the various features to be discussed. Please refer to this picture to locate all features. Figure 22 SN111 End Device The SN111 End Device provides a variety of features. These features consist of several options for supplying power, power on/off switch, an LED indicating that external power is being supplied, hardware reset button, RS-232 port, user select button and LED, a 2 digit seven-segment display, a high voltage/high current relay switch, and support of a resistive type sensor input. The SN111 End Device should not be used with SNAP Engines based on the ATMEL ATmega123RFA1, the Silicon Labs Si1000, or the CEL ZIC2410. These engines power on in a state that causes conflicts with the relay circuit on the board. SNAP Hardware Technical Manual-v1.3 Page 43 of 62

44 Power to the SN111 End Device The SN111 End Device provides two options for supplying power to the electronics. The options are: 1) wall transformer power adapter, and, 2) battery. Also, an LED is provided that lights up whenever an external power source is plugged in. Finally, there is an On/Off switch that controls power to the electronics. Notice: The power supply design used on the I/O Host Board was chosen to maximize flexibility for supporting different power supply sources. These possible sources include wall transformer power adapters that supply a range of AC and DC input voltages as well as dual and single battery operation. As a result of this flexibility on input power sources, the power supply design has not been optimized for low power operation when the RF100 SNAP Engine is in low-power modes. The power supply will draw between 50 to 100 µamps depending on the input power source when the RF100 SNAP Engine is in low power mode. A power supply design optimized for maximum power savings will draw less than 5 µamps when the RF100 SNAP Engine is in low-power mode. Power Adapter The wall transformer power adapter provided in the kit can be used to provide power. The power adapter generates 9V DC and is plugged in to the power connector. The power supply on the I/O Host Board can accept a wide range of power in to the power connector. It supports a range of both AC and DC input power meeting the following specifications: 1) AC Input power between 6VAC to 24VAC; or, 2) DC Input power between 5VDC to 25VDC. Also, there is protection circuitry if positive and negative are reversed on the plug-in jack to the power connector. The power connector is a 2mm male power jack. The wall transformer mating connector should be a 2.1mm female power plug with polarity as shown in Figure 23. Figure 23 Female Power Plug Polarity Battery Finally, AA alkaline batteries can be used to provide power to the electronics on the I/O Host Board. There is a three pin battery configuration jumper (JMP21) on the I/O Host Board that allows the user to set up for either one battery or two battery operation. If the two pin jumper provided is placed on pin 1 and pin 2 of JMP21, then single battery operation is chosen. In this configuration, the AA battery should be placed in the battery holder nearest the middle of the I/O Host Board. If the two pin jumper is placed on pin 2 and pin 3 of JMP21, then two battery operation is selected. This is shown in Figure 24 below. Page 44 of 62 SNAP Hardware Technical Manual-v1.3

45 Figure 24 Battery Configuration Jumpers In many applications where an SN111 End Device would be used, batteries will be the only source of power. Thus, maximum battery life is desired. The two battery configuration will provide twice the battery life; therefore, the SN111 End Device is preconfigured for two battery support with the two pin jumper installed on pin 2 and pin 3 of JMP21. For an SN111 End Device application where wall transformer power is being used, battery power can be used as a backup if the AC power were to go down. In this configuration, the single battery configuration should be chosen by moving the two pin jumper to pin 1 and pin 2 of JMP21. Notice: For applications where wall transformer power is being used on the End Device and battery is being used for backup power if the AC power goes down, then configure to single battery operation with the battery configuration jumper. If batteries are plugged in at the same time power is being provided by the power adapter, then special circuitry on the I/O Host Board will disconnect the battery circuit, thereby disabling the batteries from providing power. Also, there is voltage detection circuitry that allows software to distinguish between battery and external power source so that power consumption can be intelligently monitored. For battery operation, the software will detect low battery voltage and provide low battery warning indication. External Power LED Indicator The external LED power indicator on the I/O Host Board is provided to offer confirmation that the external power source is providing the proper power to the board electronics. This LED will be on if proper external power is coming in to thru the power connector. It will not be on if power is being supplied to the board by batteries. Power On/Off Switch There is a power on/off switch provided on the Interface Host Board. This switch controls power to all on-board electronics and RF Engine module except the power supply for external power and external power LED indicator. NOTICE: If external power is coming in from the power connector, the External Power LED Indicator will be ON even if the power switch is OFF. SNAP Hardware Technical Manual-v1.3 Page 45 of 62

46 User I/O There are several user I/O capabilities on the SN111 End Device. These consists of a hardware reset button, a user select button, a user status LED indicator, and a 2-digit seven segment LED display. Reset Button A user button is provided on the SN111 End Device that can be used for various select functions. User Status LED Indicator An LED is provided on the SN111 End Device that can be used for various indicator functions. 2-Digit Display A 2-digit seven-segment LED display is also provided on the SN111 End Device that can be used for displaying various sets of data and error indicators. External Port Interfaces The SN111 End Device has one external port interface. There is an RS-232 interface. RS-232 Interface The SN111 End Device has a serial RS-232 interface port. This port has a standard female DB-9 style connector. The pin assignments are shown in Table 21 below. DB-9 Pin RS-232 Signal Description Implementation 1 DCD Data-Carrier-Detect Not connected 2 RxD Receive Data Data from RF Engine (to host) 3 TxD Transmit Data Data to RF Engine (from host) 4 DTR Data-Terminal- Connected to DSR Ready 5 GND Ground Ground 6 DSR Data-Set-Ready Connected to DTR 7 RTS Request To Send Request from Host to send data 8 CTS Clear To Send Clear from RF Engine for host to send 9 RI Ring Indicator Not connected Table 21 RS-232 Pin Assignments A standard RS-232 cable for connecting the SN111 End Device to a PC has been provided in the kit. NOTICE: If the I/O Host Board is being powered by batteries, there is a power detection circuit that identifies battery as the power source and removes power to the RS-232 interface. The RS-232 interface draws several milliamps of power continuously, so it Page 46 of 62 SNAP Hardware Technical Manual-v1.3

47 would quickly draw down the batteries if left on. In order to bypass this power down circuitry to keep the RS-232 interface on, jumper 22 (identified as JMP22 RS232 PWR) on the I/O Host Board must be installed External I/O The SN111 End Device provides external I/O features. These consist of a high voltage/high current relay switch and a resistive type sensor input. Relay Switch The SN111 End Device has an integrated relay switch (normally open) and support circuitry. The relay switch can switch a load on and off that is powered by AC voltages up to 250VAC or DC voltages up to 30VDC. For either type voltage, the relay switch can handle currents to the load of up to 10 amps. The interface into the relay switch on the I/O Host Board is thru the terminal block TB1. This terminal block can accept wire sizes from 22 AWG to 14 AWG. Any type of load, either AC or DC, that falls within the voltages and current ratings listed above can be switched on and off by the relay. Examples of possible loads are: AC light fixtures or AC or DC motors. Typically, the Neutral leg of the load is connected thru the relay switch load as shown in the circuit diagram Figure 25 below. Also, the relay circuit on the I/O Host Board has a slow blow protection fuse rated at 10 Amps to protect against an overload condition. 120VAC Line (Hot) 10 Amp AC Motor M Neutral TB1 Varistor End Device 10 Amp Relay 1 10 Amp 250 V Fuse Relay Control at microcontroller on RF Engine Figure 25 Relay Circuit To access the relay, set GPIO_16 and GPIO_17 as low outputs. Pulse GPIO_17 to close the relay and pulse GPIO_16 to reset it. If you include synapse.evalbase in your script, after calling detectevalboards() you can call the setrelaystate(isset) function to control the relay. Sensor Input The SN111 End Device also has circuitry that will accept a resistive type sensor input. Examples of resistive type sensor inputs are: thermistor or photo cell. The sensor device SNAP Hardware Technical Manual-v1.3 Page 47 of 62

48 is interfaced to the sensor input circuitry on the I/O Host Board thru the terminal block TB2. This terminal block can accept any resistive type sensor directly from the sensor leads or thru wires connecting to the sensor. The wire can be any size between 28 AWG and 16 AWG. The sensor input feeds a resistor divider circuit as shown in Figure 26 below. Vp End Device Rp Sensor Input Rs TB2 Vsense Connects to an analog input of the microcontroller on the RF Engine Figure 26 Sensor Circuit Note: For shielded wire applications, the shield can be attached to the ground plane (GND) of the SN111 End Device by connecting the wire shield to pin 3 of TB2 and applying a 2-pin jumper to JMP3 on the SN111 End Device board directly above pin 3 of TB2. From the resistor divider circuit shown in Figure 26 and applying Ohm s Law, the resulting output voltage signal (Vsense) is given by the equation: Vsense = (Vp / (Rp + Rs)) * Rs Equation 1 Vsense where Vp = 3.2 VDC (Vcc of I/O Host Board) Rp = pull-up resistor defined by Table 22 below Rs = sensor resistance defined by sensor vendor resistance curves versus function sensed Vsense = analog voltage that goes to an analog input signal n the microcontroller of the RF Engine Example: A thermistor rated as 10k Ω at 25 C is connected into pin 1 and pin 2 of TB2 on the I/O Host Board. If the temperature being sensed by the thermistor is 25 C and the jumper JMP10 is installed and JMP11 and JMP12 are not installed which sets Rp as 10k Ω from Table 22, then Vsense can be calculated from Equation 1 above as: Vsense = (3.2 / ( 10k + 10k)) * 10k = 1.6 Page 48 of 62 SNAP Hardware Technical Manual-v1.3

49 The resulting voltage signal (Vsense) from this resistor divider circuit then goes to an Analog In signal on the RF Engine which goes thru a 10 bit analog to digital conversion in the micro-controller on the SNAP Engine. Using Equation (1) given above and the resistance curves of the sensor being used (values for Rs versus the function sensed by the resistive type sensor), one can generate a table showing the different values of Vsense based on the sensor condition when sampled. The resulting value returned by the 10 bit analog to digital conversion in the RF engine can be used in conjunction with this table to determine the sensor condition. There are jumper configurable options for the pull-up voltage (identified as Vp) of the resistor divider circuit of Figure 26. By applying a two pin jumper to pin 2 and pin 3 of the three pin jumper JMP8, then Vp == 3.2VDC always. If a two pin jumper is applied to pin 1 and pin 2 of JMP8, then Vp == 3.2VDC only when the RF100 SNAP Engine signal controlling the external analog source is enabled. See Figure 27 below. By controlling the pull-up voltage, power consumption can be reduced when running the I/O Host Board electronics from battery. The RF100 SNAP Engine signal controlling the external analog source would only be enabled when an AtoD conversion of the sensor input was being initiated. Otherwise, it would be disabled, removing the pull-up voltage Vp, thereby, eliminating the current drawing of the sensor input resistor divider circuit JMP8 Figure 27 Vp Jumper Controlled 3.2VDC pull-up voltage Static 3.2VDC pull-up voltage Also, there are different values of resistor pull-up (identified as Rp) by jumper configuration options. These choices of Rp are identified by Table 22 below.

50 6 Evaluation Kit SN171 Proto Board Figure 28 SN171 Proto Board This break-out/prototyping board has been created to make it easier to evaluate the Synapse RF Engine (RFE). The SN171 Proto Board provides easy access to all 19 General Purpose I/O (GPIO) pins of the RF Engine, including: 19 Digital Inputs or Outputs 8 Analog Inputs 2 UART ports Note that the analog input and serial port functionality share pins with the digital I/O you can only have a total of 19 functions at one time. Please refer to the existing RF100 SNAP Engine Datasheet for more details. On the SN171 Proto Board, none of the I/O pins is dedicated to a single function. At the same time, we wanted to make it easy to test drive "basic functionality" like blinking LEDs, reading a push-button switch, and communicating over a serial port. To accomplish this, various jumpers can be installed to connect different SNAP Engine GPIO pins to some on-board peripherals. On-Board Peripherals List From a hardware configuration (jumpering) standpoint, there are five hardware subsystems to be aware of: Page 50 of 62 SNAP Hardware Technical Manual-v1.3

53 RS-232 Port The RF Engine's UART signals are 3.3 volt logic level, and so must go through a line interface chip before they can directly be used for RS-485, RS-232, etc. The SN171 Proto Board includes a RS-232 line driver that can optionally be used with UART 1 (SCI 2). Note that this is the second serial port of the RF100 SNAP Engine. The first RF100 SNAP Engine serial port is always 3.3 volt logic level.

Figure 32 RS-232 Jumpers Locations Connectivity Options Two terminal blocks (one on each side of the board) provide access to all of the GPIO pins, plus various POWER, GND, and RESET signals. SNAP Hardware Technical Manual-v1.3 Page 53 of 62

54 NOTE that these terminal blocks DO NOT have the exact same pinout as the two headers on the RF Engine! The RF Engine headers have 24 pins total, the breakout board terminal blocks have 28 pins total. The extra pins are additional GND and POWER connections. Notice the power (VCC) pin between GPIO6 and GPIO7. Figure 33 GPIO Terminal Block 1 Figure 34 GPIO Terminal Block 2 Also notice the power (VCC) pin between GPIO14 and GPIO15, and also one next to GPIO18. In addition to the two terminal blocks, these signals are also available at connector J2 (if loaded) as described in Table 27.

61 9 SS200 SNAP Stick Introduction Figure 39 An SS200 SNAP Stick The SNAP Stick 200 is based on the ATMEL ATmega128RFA1 hardware. It is a USB dongle, about the size of a thumb drive, designed to act as a bridge between Portal or SNAP Connect and your GHz wireless network. Because it is based on the ATmega128RFA1, the SS200 has the same capabilities as the underlying hardware, relating to sleep options and radio rates. The USB dongle form factor means that only one UART is available on the SS200. UART1 connects through the USB port. Also because of the form factor, you do not have normal access to the GPIO pins on the SS200. The device was designed to primarily act as a bridge device, or as a repeater node (powered with a USB AC adapter) for adding hops to extended network topographies. The only feedback available from the device comes in the form of a tri-color LED, controlled by pins 5 and 6: LED State Pin 5 Pin 6 Off High (True) High (True) Red Low (False) High (True) Green High (True) Low (False) Amber Low (False) Low (False) The SS200 includes an internal power amplifier. It also has a 32 khz crystal, so for most efficient sleep you should use sleep mode 1. SNAP Hardware Technical Manual-v1.3 Page 61 of 62
