Port expansion for the DB15 connector of my Max series controllers version 3.6 or 4.x. The PCB is sized to fit within the plastic shell of one of these.
This has a pair (Axis1 and Axis2) of inputs to carry A/B quadrature signaling from encoders. It also has level conversion so the encoder input pins going to OnStep's Smart Web Server are 3.3V level.
Additionally there are connections (most can be used for other purposes too) for:
