This Arduino shield from Adafruit features TI’s CC3000 Wi-Fi module with an onboard ceramic antenna, a microSD card socket, and a designated prototyping area. The CC3000 uses SPI for communication instead of UART, so the communication speed is not limited to a fixed baud rate. It supports 802.11b/g, open/WEP/WPA/WPA2 security, TKIP, and AES, and a built-in TCP/IP stack with a BSD socket interface supports TCP and UDP in client and server mode with up to 4 concurrent socket connections.

Description: 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.
