Description

Embedded TCP/UDP stack - allows you to upload data to a web server | RTC supported| Selectable serial port | Speaker and Headphone jac Note: This is new version (version 64M), SMS MMS support:multimedia message and Short Message Service - so that you can send small amounts of data over the network (ASCII or raw hexadecimal) 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 on-board.
