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:
The new electronics are all placed in the box below the radio:
And it is based on an Arduino MEGA:
To which are connected LCD panel and power supply:
Sticks, switches and buttons:
There is also a MicroSD reader:
The antenna is for a 2.4 GHz transmission:
The transmission module box is also printed with my 3D Printer:
There is a button for the bind between the radio module and the receiver:
The radio module is a Multiprotocol TX Module and it is based on an Arduino Pro Mini and on a CC2500 PA LNA module:
An indication LED is present:
The battery is a LiFePO4:
Radio documentation is available on the OpenTX website .
