4 Frequency GPRS/GSM Module-is an ultra compact and reliable wireless module. It is a breakout board and minimum system of SIM900 Quad-band GSM/GPRS module. It can communicate with controllers via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands). This module support software power on and reset.
The GPRS is configured and controlled via its UART using simple AT commands. Just connect on the Arduino/PIC/AVR/ARM/FPGA/CPLD board, you could easy to use AT command control it. The module can be connect to PC via FTDI
