hi have a problem with my micro v4.1 with cytron
was is rqh 1000300 pin 1gnd signal pin4 5vpin5
it will only work when a2d convertor is set to differential
on single gauge was fixed volt eg 4.2v and no reaction when I turn the steering wheel
but I set the a2d convertor to differential
then the control works and can get it up and running
