SIM808 GSM + GPRS + GPS Cellular Module [Discontinued] _ARD_COMPAT_UNO This includes the original PiThe SIM808 GSM GPRS Module is at the heart of our Adafruit FONA 808 Mini Cellular GSM + GPS Breakout. For people who want to integrate a cellular (GSM GPRS) module into their design without the full breakout, this hand solderable module is pretty nice! Please note we don't provide any tech support for this module, but we do have a schematic as well as a collection of datasheets and app notes that can be used to interface. Quad band 850 900 1800
