MOD-GSM-EDGE is designed for adding remote monitoring and control via GSM cellular network. With this module, any board that has a UEXT connector (see below) can give you access to its features via the GSM network. MOD-GSM-EDGE also can be connected to a PC directly via USB.

MOD-GSM-EDGE features a SIM700D quad-band (850/900/1800/1900 MHz) GSM GPRS/EDGE module, which covers most GSM networks around the world. The SIM700D supports the EDGE protocol which assures faster data transfer. The GSM antenna is built into the board, so there's no need for an expensive external GSM antenna.

This module can work in stand-alone mode also, but only when the SIM card is without PIN code. In stand-alone mode, MOD-GSM-EDGE requires use of AT commands. It can receive information via GSM, but if you want to do anything with this information, you will need to connect it to an appropriate controller board with UEXT. Choose the controller board based on the needs of your application.

Note: The MOD-GSM-EDGE is not FCC approved. The GSM modem itself has FCC approval, but the entire board does not. If you're in the U.S., this means you can only use this board for evaluation and your own development. If you want to sell this unit to end users, you will have to get your entire application FCC approved before doing so.

To use the GSM modem function, you need to subscribe to or get a pre-paid card from a mobile phone service provider that has a GSM network (in the U.S., AT&T or T-Mobile). The GSM SIM card needs to be inserted into the GSM modem's SIM card holder.
