Description
The module working with Arduino and Raspberry Pi that provides communication in GSM and GPRS standard. It allows for voice chat, sending SMS messages and transfer of data. On the board are: two connector for SIM cards (dual SIM), microSD slot which allows you to storage the data, output and input of audio in the Jack 3.5 standard to connect headphones and microphone, and a U.FL slot for mounting externalantenna(in our offer, you will find the appropriateadapters).

GSM shield in combination with the Arduino Uno board.
The connection to the Arduino
The system works as a shield for Arduino, using the following lead:
| Pin | Arduino | Description |
|---|---|---|
| GSM RX | D2 | Communication via the serial interface. |
| GSM TX | D3 | Communication via the serial interface. |
| PWRKEY | D7 | The control of the power supply of the GSM system (On/Off). |
| STATUS | D5 | The status lead. |
| RESET | D6 | GSM system's reset. |
|
ARD-RESET |
RST | Output RESET of the Arduino. |
