Arduino GSM/GPRS Shield

The GPRS Shield is compatible with all boards which have the same form factor and pinout as a standard Arduino Board. The GPRS Shield is configured and controlled via its UART using simple AT commands. Based on the SIM900 module from SIMCOM, the GPRS Shield is like a cell phone. Besides the communications features, the GPRS Shield has 12 GPIOs, 2 PWMs and an ADC.



  • Because SIM900 peak current more than 2A. This shield must work with a external DC9V power supply.
  • If you are using MEGA2560. Just need to connect the middle pins of RX and TX jumpers to RX1 TX1 on Arduino Mega 2560. And change the code setting.



  • Based on SIMCom's SIM900 Module
  • Quad-Band 850 / 900/ 1800 / 1900 MHz - would work on GSM networks in all countries across the world.
  • Control via AT commands - Standard Commands: GSM 07.07 & 07.05 | Enhanced Commands: SIMCOM AT Commands.
  • Short Message Service - so that you can send small amounts of data over the network ASCII or raw hexadecimal.
  • Embedded TCP/UDP stack - allows you to upload data to a web server.
  • Speaker and Headphone jacks - so that you can send DTMF signals or play recording like an answering machine.
  • SIM Card holder and GSM Antenna - present onboard.
  • 12 GPIOs, 2 PWMs and an ADC all 2.8 volt logic - to augment your Arduino.
  • Low power consumption - 1.5mAsleep mode
  • Industrial Temperature Range - -40°C to 85 °C




• 1x Arduino GSM / GPRS Shield
