Hi all,

I just connected my Turnigy IA6C to BF Omnibus F4 Pro V2 to SBUS-PPM/5V/GND but when I
turn on the Turnigy Evolution transmitter, the screen flashes, gimballs red and RX icon flashes empty...?
I measure 4.5V on the board when connected to PC with USB and lipo powered. Only lipo powered I measure only 3.7V.
I remeasured and it seems I get 3.7 everywhere... the lipo connection on the fc has 4.9v, guess it has something to do with
the FC BEC?
The strange thing is that when the FC is connected to a PC and I have the transmitter on, it works.
Also, do I set it to SBUS or iBUS?

Can't seem to find anything about it?

Thanks guys

Solved.

The FC I have needs raw LiPo voltage to run through the currency meter and provide 5v using the FC built-in BEC.
