PWMA and PWMB to Vcc (orange wire)

Then hook one stepper motor coil to Motor A (red and yellow) and the second coil to Motor

B (green and gray/brown). If you have another motor, you'll need to experiment a little to

figure out which wires are which coil. Check any documentation you have! You can use a

multimeter to measure between wires, the ones with a small resistance between them are a

pair to a coil, for example. If the motor is vibrating but not spinning, check all wires are

connected and try flipping around a pair or rechecking the wire pairs.

If you have a unipolar motor, there will be a 5th or 6th wire that is the 'common' wire.

Connect these wires to the GND pins in between the Motor A and B outputs on the

breakout.
