TX Module pin-out

Post by Sangoma »

Somewhere I had a circuit diagram someone had made of the TX module, but can't fine id, and can't find it on Google.

I need the pin-out of the module, 3 are obvious on the TX end, the two grounds and the 35MHz antenna.

I need to know the other two, and also if the two grounds are connected inside the module (that I can find by opening a module, but if anyone has any experience of disconnecting one, it would be useful)

Thanks

Yep the +6V pin is grounded both in the radio and module. Many people including me isolate it and reuse the ANT and +6V pins to carry the 2 telemetry signals to an FrSky DJT module.
