The IoT Bit GSM HAT connects to the Raspberry Pi board using a 40-pin GPIO header and features an autoconfiguration system that allows automatic GPIO setup and driver setup. The IoT Bit GSM HAT easily gives a single-board computer powerful connectivity anywhere. The IoT Bit can integrate easily with the software on an operating system giving access to general internet data through the mobile network. Using the Altitude Application Programming Interface (API), the IoT Bit GSM HAT sends SMS (text) messages and communicates over Bluetooth. It also gives easy access to the onboard GPS for location data.
