The NucleoTNC is a breadboard implementation of our commercial product, the Mobilinkd TNC3, designed to encourage experimentation and learning in amateur radio, electronics, digital signal processing and software engineering.

The TNC can be built with about $25 in parts. Build instructions, schematics in KiCAD format, and source code are available from our public GitHub repo.
