The ArduinoTrack Flight Controller is an Atmel ATMega328p based microcontroller, that fits on the Arduino Shield form factor. It can be used as a Shield to enable APRS position reporting to an existing Arduino, or it can be used by itself as a stand-alone APRS beacon.

The ArduinoTrack is open source hardware and software, and can be built by yourself from scratch, by purchasing a kit of parts, or by purchasing an assembled kit from Custom Digital Services.
