Product description: GSM LTE NB IoT EGPRS GNSS module - u-GSM shield v2.19 BG95M2 - for Arduino and Raspberry Pi - u.FL connector
The u-GSM shield module with the BG95M2 chip allows for communication in the GSM, LTE, NB IoT standard. With it, you can make voice calls and send SMS text messages . The GNSS system supporting GPS and Glonass satellites is responsible for the better signal and accuracy. On the board you can find a SIM card slot, a Li-Pol / Li-Ion battery charger system, communication interface connectors, u.FL antenna connectors and a Reset button. The module works with Raspberry Pi , Arduino and BeagleBone . The board supports active and passive GNSS antennas.
A detailed description of the module can be found in the user guide in the first and second parts and on the manufacturer 's website.

Connection of u-GSM Shield with Arduino
The system works with the Arduino Uno using the following conclusions:
- GSM RX (pin D3) - Communication via the serial interface
- GSM TX (pin D2) - Communication via the serial interface.
- RESET (pin D6) - GSM system reset.
- Ena (pin D7) - GSM system supply voltage control (On / Off).
- VIN (5V LiPol) - (5V pin) - 5V power supply. Connection details for LiPol batteries are available in the manufacturer's manual.
- GND (pin GND) - The ground of the system.
- STATUS (pin D5) - Status output.
GSM module compatible with Raspberry Pi.Connection of u-GSM Shield with Raspberry Pi
The module has special, broken-out connectors that enable direct plugging into the GPIO connectors of the Raspberry Pi or BeagleBone Black.
In order to run the module with Raspberry Pi, make the following connections:
- GSM RX (pin 10) - Communication via the serial interface (not connected for USB communication).
- GSM TX (pin 08) - Communication via the serial interface (not connected for USB communication).
- RESET (pin 18) - GSM system reset.
- ON / OFF (pin 16) - GSM system supply voltage control (On / Off).
- VIN (5 V LiPol) (pin 02/04) - Supply voltage 5 V.
- GND (pin 04/14) - The ground of the system.
- STATUS (pin 12) - Status output.
