Omnibus F4 Pro AIO V2 PPM/SBUS issue
« on: August 01, 2017, 01:44:19 PM »

As the title says: I cannot get the board to see the XSR in either PPM or Sbus mode. I have tried every combo I can think of to connect to UART 1. There are 2 pads next to UART1 but all info I can get cannot agree as to if they need soldering or not. Any help or advice very welcome!

If it's anything like the Omnibus F3 you need to remove the 0-ohm link on whichever one you are not using.

That's what I thought but many say it's not necessary on the v2. And they are  not labelled so no idea which is which.

Turns out that the printed circuit from the ppm connection had been broken by previous owner clumsy soldering. I scratched the surface away until I could see the wire and then blobbed solder onto it. A bodge but it works at the moment.
