Arduino Sheilds
SIM900 GPRS/GSM Arduino Shield Development Board (Quad Band)
The GPRS Shield is based on SIM900 module from SIMCOM. The GPRS Shield provides you a way to communicate using the GSM cell phone network. The shield allows you to achieve SMS, MMS, GPRS and Audio via UART by sending AT commands ( GSM 07.07 , 07.05 and SIMCOM enhanced AT Commands). The shield also has the 12 GPIOs, 2 PWMs and an ADC of the SIM900 module (they are all 2.8V logic) present on-board.
