Just saw this . Very useful. I tested my hall sensor with multimeter. On connection to black and brown I get the 4.5v which seems the input voltage. When I connected blue and black I have 4.0v and when magnet passes by I get 3.71v, is this working okay?

Could I ask where you got the hall sensor from? Might worth the try before buying a RCexl CDI
