GSM / GPRS Shield

This product is currently sold out.

The GPRS/GSM Shield provides you a way to use the GSM cell phone network to receive data from a remote location. The shield allows you to achieve this via any of the three methods:

  • Short Message Service
  • Audio
  • GPRS Service

** Compatible with 2 degrees and Vodafone. (Quad-Band 850 / 900/ 1800 / 1900) **

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 the SIM900 peak current is more than 2A it is recommended that you use an external DC9V power supply.

Features:

  • 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.
  • 12 GPIOs, 2 PWMs and an ADC (all 2.8 volt logic) - to augment your Arduino.
  • Low power consumption - 1.5mA(sleep mode)
  • Industrial Temperature Range - -40°C to +85 °C
