GPRS Shield V2.0: bring your Arduino project into the 2G+ age!

The Seeed Studio GPRS Shield V2.0 module acts as an interface, allowing your Arduino project (or other compatible board) to exchange data over a mobile phone network. Based on the SIM900 circuit released by SIMCOM, it requires use of a SIM card (not included).

You can control the shield with your Arduino Uno, Mega 2560, Seeeduino or Seeeduino Mega board using the SIMCOM AT commands. Your Arduino shield is also equipped with 12 input/output pins, 2 PWM outputs, 1 two-in-one headset jack and 1 analogue-to-digital converter output. If you want a more powerful signal, a connector for an external antenna is available in addition to the built-in GPRS antenna.

Uses for the Seeed Studio GPRS Shield

Add a GPRS module to your Arduino or Seeeduino project, and you’ll open the door to a whole new range of possible applications:

  • Transfer data between 2 machines;
  • Exchange SMS messages and telephone communications;
  • Create a GPS with the addition of a GPS module;
  • Create an interactive answering machine with the addition of an MP3 module and DTMF decoder;
  • Control your project remotely by SMS;
  • And the list goes on!
