The GPRS Shield is based on SIM900 module from SIMCOM and compatible with Arduino and its clones. 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 2V8 logic) present onboard.
Note: The SIM900 Board Input is 5-26V 2A, Recommended current is not more than 9V 2A. GPRS Shield Communication baud rate is 19200 BPS 8-N-1.
