OK no problem Max, I can do that
So first, I put the aq on power this my lipo 4S.
at this moment the red led power was on red without blinks.
After that I connect my aq board to pc with ftdi usb. I put a jumper connector on J4 too.
After that I check my port com and my pc find the ftdi adaptater.
I choose the right port com, the baud raid following the wiki autoquad.
And when I press "connect" there were an error, my aq was not find by the qground control.
I have an other advices to ask you, it's for powering my boards.
I don't know how I can power the ESC32s and the AQboard in the same time to my lipo and I don't know if I have to use UBEC 5V or not ? Could you drive me for this point, I'm a really bad electonician
