The IoT Bit 4G 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 4G HAT easily provides single-board computer powerful connectivity anywhere. The IoT Bit can integrate easily with the software on an operating system giving access to fast internet connectivity for web browsing and data transfer. Using the Altitude Application Programming Interface (API), the IoT Bit 4G HAT allows downloading large files, streaming video, and more. It also features onboard GPS for location data and battery support.
