Hello Piing
when it comes to powering arduino board in the DIY FC, it should be ok to power arduino board via usb by hooking it to the laptop usb port right ?
because when i did that it seems like there's no signal going from the FC to the Axe fx II at all, nothing is responding. what could be the problem ?
I posted the instructions to use the FCB1010 with the Axe-FX III here:
