Connecting the 2G/GSM module with Arduino
The system works with Arduino using the following pins:
- GSM RX (pin D3) - communication via serial interface
- GSM TX (pin D2) - communication via serial interface.
- RESET (pin D6) - reset the GSM system.
- ENA (pin D7) - control of the power supply voltage of the GSM system (On/Off).
- VIN (5 V Li-Pol) - (pin 5 V) - supply voltage 5 V.
- GND (GND pin) - system ground.
- STATUS (pin D5) - status pin.
Connection of the 2G/GSM module with Raspberry Pi
