I built a TNCPi, which as the name suggests is a TNC for the Raspberry Pi. It has the same footprint as the Pi, takes power from it, and plugs straight into the GPIO pins.
The TNC appears as a serial device on the Pi, /dev/ttyAMA0, with the data rate fixed at 19200 baud, and the on-air data rate is fixed at 1200 baud.
Note the DB9 connector on the photo: it's used to hook up the radio.
It even worked the first time I powered it up! Assembly is a breeze, I'd call it a one evening project. Only basic tools are needed, and the documentation is good. All of the components are provided with the kit.
