Description

The new version of the module working with Arduino and Raspberry Pi that provides communication in GSM and GPRS. Based on Quectel M95, it allows for voice calls, sending SMS messages and transfering data. On the board are: 2 slots for SIM-cards (dual-SIM), slot for microSD cards which allows you to save the data, output and input audio in the standard Jack 3.5 for headphones and microphone and a slot u.FL for external antenna (in our offer, you will find the appropriate adapters).

The modified control signals

POWER and RESET

By default, low status

activated with high position

By default, high status

activated with low state

Connecting connectors microUSB miniUSB
Working voltage of UART from 3.3 V to 5 V from 2.8 V to 5 V
The number of ways of powering 3 5



The device requires a good quality of supply. We recommend the use of an external power supply of min. 5 V / 1 A when powered from USB or the 12 V / 500 mA when powered by Vin. You should not power the shield from the USB port of the computer.

 

The connection to the Arduino

The system works as a shield for Arduino, using the following conclusions:

 

Pin Arduino Description
GSM RX D2 Communication via the serial interface.
GSM TX D3 Communication via the serial interface.
PWRKEY D7 Control of the supply voltage of system GSM (On/Off).
STATUS D5 The statuspin.
RESET D6 GSM system's reset.

ARD-RESET

RST Led out RESET of the Arduino.

5V

5V The supply voltage of 5 V.

Vin

Vin The input voltage Vin.
GND GND The groundof the system

 

Examples of projects for Arduino:

 

Connect to the Raspberry Pi

To launch a module with the Raspberry Pi, you must perform the following connections:

 

Pin RPi Description
GSM RX 08 Communication via the serial interface.
GSM TX 10 Communication via the serial interface.
PWRKEY 16 Control of the supply voltage of system GSM (On/Off).
STATUS 12 The statuspin.
RESET 18 GSM system reset.

5V

02/04 The supply voltage of 5 V.
GND 06/14 The groundof the system

 

Example of programs for the Raspberry Pi:

 

Package width 5.5 cm
Package height 0.2 cm
Package depth 8.5 cm
Package weight 0.027 kg
