, LTE Cat. M1, Cat.NB1, EGPRS, NB-IoT Arduino shield 2 Interfaces 2.1 Power Module supply input The shield must be supplied through the VCC pins by a DC power supply with nominal voltage of 5V to 12 V. Voltage must be stable during module operation, taking into account that the current drawn from VCC pins may vary significantly based on the power consumption profile of the NB-IoT system. Digital I/O interfaces supply output (V_INT) The shield provide an internally generated supply rail output (V_INT) operating at 1.8 V. This can be used in place of an external discrete regulator to supply external digital interfaces. The voltage level present at the V_INT pin depends on the module operating mode: - In the deep-sleep mode the voltage level is kept Low (i.e. 0 V) - In active and connected modes the voltage level is maintained High (i.e. 1.8 V) 2.2 Antennas The uses 2 antennas, 1 GPS antenna and 1 GSM antenna. The GPS antenna is integrated on the PCB but also an external GPS antenna can be used by connecting it to the U.fl connector. And the GSM antenna needs to be connected to the SMA of U.fl connector. It is important to note that the antennas can t be too close to one another, because they will cause interference. This causes problems when using the GPS function of the shield. 2.2.1 GPS_ANT The GPS antenna has been tuned with a LC Chebyshev filter to gain optimal performance. The center frequency is around 1575 MHz. 2.2.2 GSM_ANT (ERF4041 GSM antenna) The ERF4041 antenna is a black GSM antenna a SMA Male connector. The antenna can be used in the frequency band of 800~840 / 1640 / 2200~2230 / 3410 MHz. The antenna can be used for applications, GSM, M2M and more.

, LTE Cat. M1, Cat.NB1, EGPRS, NB-IoT Arduino shield Option 1 and 3 are not recommended because the USB can t supply enough power for some functions of the BG96 module on the shield. this may cause damage to the shield or to your USB power supply. 2.4 Status LED s The shield also has 3 LED s to give an indication of the status of the shield. Led Color State Description PWR Green Always on Shield is powered Always off Shield is not powered Stat Red 0.2s on/1.8 off Searching for network 1.8s on/0.2s off Idle mode 0.125 on/0.125 off Data transfer is ongoing with GSM/3G/4G network Net Yellow Always on Registered to 3G network(uc20) Registered to 4G network(ec20) Always off Others 2.5 SIM interface To register and connect to a network a SIM card needs to be inserted and activated. When a activated SIM is inserted, the correct APN must be set using AT commands. For more information see: Quectel_BG96_AT_Commands_Manual_V2.0.pdf Page 9 of 16
, LTE Cat. M1, Cat.NB1, EGPRS, NB-IoT Arduino shield 2.6 UART interface Rework 2.7 Programming the shield There are 2 ways to program the. The first and most easy way is to use the Qnavigator software developed by Quectel. In this software you can send AT commands via the PC. The second way to program the shield is via an Arduino. if you choose to program the shield via an Arduino you can add your own custom sensors and build your own application. 2.7.1 Programming the shield via Qnavigator Before connecting anything first check if the headers are in the correct position. The Vin header should be on PWR if a power adapter is being used. When this is the case, remove the USB PWR header. If no power adapter is used, set Vin on 5V and connect the USB PWR header. Now connect the USB cable to the device and to the PC. The green LED will light up. Now press the Power switch for 3 seconds. The Stat LED should light up and the Net light should start blinking. Now the correct drivers need to be installed on your PC. These can be found here Also the Qnavigator software needs to be installed. this can be found here When the installations are done, the PC will recognize the shield. To verify this go to, device management and look for the following 3 ports. Now open the Qnavigator software and follow the instructions shown in the program. Page 10 of 16

M1, Cat.NB1, EGPRS, NB-IoT Arduino shield 2.7.2 Programming the shield via Arduino //to do testen met Arduino Before connecting anything first check if the headers are in the correct position. The Vin header should be on PWR if a power adapter is being used. When this is the case, remove the USB PWR header. If no power adapter is used, set Vin on 5V and connect the USB PWR header. Now connect the USB cable to the device and to the PC. The green LED will light up. Now press the Power switch for 3 seconds. The Stat LED should light up and the Net light should start blinking. // Once this is done, download the Arduino IDE software on your PC. This can be found here: https://www.arduino.cc/en/main/software. To communicate with the shield a standard Arduino library called SoftwareSerial is needed. This is already installed with the Arduino IDE. Information can be found here: https://www.arduino.cc/en/reference/softwareserial Once Arduino IDE has finished installing open the software. 2.8 GPIO The shield has multiple GPIO pins. The GPIO header* has all the GPIO pins from the BG96 module. The Arduino headers 1 and 2* have the normal Arduino GPIO pins, if the module is used in combination with a Arduino. This allows for the possibility to add extra functionality to the shield, and integration in your application. *the GPIO and Arduino header pinout can be found in chapter 3 Pin Assignment Page 11 of 16
