Hello,

I am getting back to drones and bought a Radiomaster Boxer with ELRS.

My question: 
Could you please give me a hint how I wire the RP1 ELRS receiver to the AIO F45 board?

I attach both pics.

I bought a Foxwhoop 25 with an XM+ receiver but I cannot bind it to my Taranis X9D+. It is frustrating. 10 hours of work and no result... So I replace the Taranis and the XM+ with a ELRS receiver and a new sender. Hope that is better.

Many thanks four your answer.

I am just using UART 4 as an example because it looks the easiest. But you can use any of the other UARTs.

ELRS - - - >FC
Ground - - - > Ground
5V - - - > 5V
TX - - - > RX4
RX - - - > TX4
