Thanks for your prompt response. I still don't understand why you design a PCB for an older and less robust protocol and not provide support for newer better serial based protocols, especially since it would allow for 2-way communication. Is there any other way to control the PXFmini via sbus other than handicapping by converting to ppm?
edit Im thinking something along the lines of a serial-converter on the rpi
edit #2 Also, your competitor the Navio2 supports sbus..
edit #3 sorry for all the edits, this post the schematic shows pin 7 as S.Bus/PPM input?
