Hello.
I want to connect to an ELRS transmitter (pet-project)
I need documentation on how to connect the ELRS transmitter to the remote control. Specifically:

JR Bay pinout
How the channels are transmitted from the remote control to the external module. As I understand it, CRSF is used, so apparently I need CRSF documentation
How are the commands transmitted to configure the ELRS external module

Can I get it?
