Step/direction inputs
The motor angle step with the rising edge of the STEP signal, the
direction of rotation is controlled by the DIR signal.
Step and Dir outputs from the four motor ports are open collector
outputs. Absolute maximum current is 40 mA, so depending on what
voltage you use, and on your stepper driver electronics (diagram only
shows an example) you may need to add some resistance (R) on the cable.
It is possible to use higher voltage as long as the current is kept within the
limit, but it is highly recommend to use 5V output from MRMC Quad
board (pin3). Absolute maximum is 24V, and should never be exceeded.
