Reference Design #42

Open bennymeg opened 2 years ago

bennymeg commented 2 years ago

I would like to design my own transmitter and receiver. Do you have a reference design or minimal schematic that I can base on?

Do you want to build a module or a full transmitter?

I would like to build a transmitter, and I would like to use supported MCU & transmitter ic combination.

Check out my repo https://github.com/kkbin505/Arduino-Transmitter-for-ELRS/tree/VSCODE

It use arduino nano, and is the simplest desgin I can implement

Thank you, but what I meant is that I want to build the transmitter (like you built a DIY one) that I can download an unmodified firmware from the ELRS configurator. So, what I am actually what to know is where can I find a description of the firmware compatibility.
