What WAS sensor for rqh100030 on PCBv2 you connect it like this:
If you change wires you get random high output. Try measuring voltage at output pin when rod is 90deg from connector it should be 2.5v
If you power PCB from USB you will get small fluctuations (0.2deg±) if you power from 12v WAS should be stable.
IF WAS reading freezes reconnect in AGio.
