retrolefty:
I'm still going with two channel outputs, mostly just based on the number of wires connecting the module. A speed sensor would only need/use three, ground, power, and signal.Lefty
So oscilloscope trace for white/ground would give one channel pulses trace and blue/ground would give the other channel pulse trace? I did try that already and got no obvious pulse trace on the scope unless I used blue/white... or am I just doing something really stupidly wrong?
