Now we need to wire up our external driver breakout board.
3.3V and GND (Note: The pin labelled 5V on the breakout board must be connected to 3.3V on the Duet, not 5V!)
12V/24V (vin) and GND
ESDG wires (Enable, Step, Direction, Ground)
Note: It’s strongly recommend clearly marking your wires, so as not to short out something or otherwise plug them in improperly!
