Mega2560 Radio - Mazzo.me

I made this radio using the mechanics of an old analog radio and adding a new electronics based on an Arduino with firmware OpenTX.

To be able to manage the radio I added an external box printed with my 3D Printer which contains the electronics and mounts buttons, as well as an LCD panel:
