SIM900 GSM / GPRS Arduino Shield


Package Includes

  • 1x SIM900 GSM / GPRS Arduino Shield

Availability: 1 in stock

This GSM / GPRS Shield is based on the SIM900 module from SIMCOM and is compatible with the Arduino Uno and its clones. It provides you with a way to communicate wirelessly via the same network infrastructure that cellphones use. With this shield you will be able to add SMS, MMS, voice, and GPRS capabilities to any standard Uno board. The SIM900 module is typically controlled via UART with the help of a particular set of AT commands (GSM 07.07, 07.05 and SIMCOM enhanced AT Commands). In addition, 12 GPIOs, 2 PWMs and an ADC input from the SIM900 have been broken out to pin headers on the shield and are quite easy to access.

Note: You will need a standard size SIM card (Not micro or nano) to connect to a GSM / GPRS network
