Table : Jumper positions for battery powered operation with a protection diode, two jumpers are optional.. External supply When measuring current consumption or performing other NIN-B module characterization measurements, it can be useful to power the module with an external source such as a DC power analyzer. In such a case, all jumpers can be removed and the required supply nets can be fed externally by connecting to the pin headers. For example, the NIN-B module can be powered by connecting an external supply directly to the J pin and GND. Take care that unpowered parts of the board are properly isolated. If a voltage is applied to the signal of an unpowered device, current might leak through various protection circuits of the device. This might give false readings when measuring current consumption etc. Figure below shows a few optional jumper connections that can be helpful when supplying the module with an external supply.

14 EVK-NIN-B - User Guide.. rduino shield compatibility The EVK-NIN-B has an I/O voltage range of.-. V. It can therefore be used only with shields that also support an I/O voltage within this range. The EVK-NIN-B has a pinout that is compatible with some rduino or rduino inspired shields. This section describes the features of the EVK pins that a shield must comply with: IOREF: The I/O voltage level of the NIN-B module is. V by default, but the EVK can be modified to allow other voltages (.-. V). RESET: Is connected to the RESET button (SW0).. V: regulated. V output. Should not be used as a voltage supply input, use the VIN pin instead. V: Is only a V supply output if the EVK is being powered by USB. If any other power configuration is used, this pin will be unconnected (floating). It is safe to connect an external V supply to this pin even when a USB cable is connected. This pin cannot be used to power the board, use the VIN pin instead. VIN: May be used as a - V supply input to power the EVK-NIN-B. Pin 0 (RX): Is connected to the NIN-B URT RX pin (NIN pin ). Pin (TX): Is connected to the NIN-B URT TX pin (NIN pin ). Note on SCL/SD: On some rduino boards, the I C signals, SCL, and SD are connected to the pins and and to the SCL and SD pins in the top right hand corner. Since these pins will be shorted together it might cause problems when connected to the EVK-NIN-B, which has not shorted these pins together. Note on digital I/O pins: Some of the digital I/O pins can be connected to the on-board debug MCU, thus allowing serial communication and flashing/debugging over USB. This can cause interference on the signals that are also used by an rduino shield. See section.0 on how to disconnect these signals from the debug MCU.. Raspberry Pi compatible interface The EVK-NIN-B includes a 0-pin GPIO header that can be used to interface with either a Raspberry Pi computer board or with a Raspberry Pi expansion board (HT). The EVK-NIN-B uses different hardware and software configurations depending on if it is connected to a Pi or a HT; the differences are covered in this section. The default configuration is to connect to a Pi. Not all the Raspberry Pi versions and HTs are supported, since it requires the 0-pin GPIO header, which older versions did not have.

Powering considerations There are two voltage nets used in the Raspberry Pi interface - V_PI and V. Both the V_PI and V nets can be used to power HTs, but should not be used when connecting to a Raspberry Pi. See section.. for more information. The V_PI power net must not be connected to the. V supply when connected to a Raspberry Pi board. It could damage both the boards... URT The Raspberry Pi interface provides two pins that can be used for URT communications GPIO and GPIO. In URT communications, signals are always connected RX <-> TX and vice versa. This means that on a Raspberry Pi board GPIO will be TX and on a HT it will be RX. To support talking to both HTs and Pi boards, the zero Ω resistors - R, R, R and R0 can be used to toggle the NIN TX and RX pins between GPIO and GPIO. If a NIN-B0 is used, this switch can also be made in the software. By default, the EVK-NIN-B will be configured to simulate a HT, and GPIO is connected to the NIN URT_RXD pin and GPIO is connected to the NIN URT_TXD pin...0 EEPROM support The Raspberry Pi interface supports a unique EEPROM solution to store the HT specific GPIO configurations on the HT board, to be read by the Raspberry Pi before configuring its GPIOs. The two pins used for this - ID_SD and ID_SC, are connected to the NIN-B module. The NIN module can thus either read the GPIO configuration from a HT, or simulate an EEPROM and send configurations to a connected Pi. This requires a NIN-B0 module and a custom built application. It is not mandatory to use this EEPROM solution; if not used, the two NIN pins GPIO_ and GPIO_ can be left unconfigured. Two pull-up resistors - R and R0, can be added to the I C lines if needed. They are not mounted on the evaluation board by default. Visit for more information on the ID EEPROM specification. UBX-0 - R0 Product description Page of 0

21 EVK-NIN-B - User Guide Setting up the evaluation board. Evaluation board setup The EVK-NIN-B will be delivered with the u-blox connectivity software installed on the module. Before connecting the module, download and install the latest u-blox s-center evaluation software from the u-blox website. To use Bluetooth Low Energy on the EVK-NIN-B, connect a. GHz antenna to the U.FL antenna connector (J0). The EVK-NIN-B has an onboard antenna. Plug in either an external power supply in J connector or connect to a USB host with a USB cable attached to J connector. You can also power the evaluation board with a CR0 coin cell battery. The status light (DS) will turn green, indicating it has power. The NFC antenna can be connected to the J connector. Be careful to check polarity before connecting an external power supply to the EVK-NIN-B evaluation board. Center conductor is positive (+) and the ring is negative (-). The operating system will install the correct drivers automatically. The drivers will only need to be installed the first time you connect the unit to a new computer. If the drivers are not installed automatically, download the nrfgo Studio from to get the Jlink CDC URT driver. COM port will automatically be assigned to the unit by Windows. Do the following to view the assigned COM ports on Windows : Open the Control Panel and click Hardware and Sound. Click Device Manager in Devices and Printers. This will open Device Manager window where you can view the assigned COM ports.. Starting up.. EVK-NIN-B and EVK-NIN-B Perform the following steps to enable communication with the module:. Start the u-blox s-center evaluation software.. Use the default baudrate 00, N with flow control.. You will now be able to communicate with the module through T commands. For a list of available T commands, see the u-blox Short Range T Commands Manual []. To get started with basic use case set up of the EVK-NIN-B with u-blox connectivity software, see the NIN-B Getting Started []... EVK-NIN-B0 and EVK-NIN-B0 If you would like to use the EVK-NIN-B together with Nordic Semiconductor SDK, refer to the Software section of the NIN-B System Integration Manual [].. Getting the latest software Go to the u-blox support webpage to obtain the latest available firmware. Instructions on reflashing the EVK-NIN-B can be found in the Software section of the NIN-B System Integration Manual []. UBX-0 - R0 Setting up the evaluation board Page of 0
