When my new driver board arrives Monday (the one thats the same as yours) I’ll get it up and running and send you the wiring diagram and instructions.
Cheers

than why don't you invest in a pulse generator of some sort instead of trying to re-invent the wheel!

Hi SACC52- The video you saw uses AC. This means the motor can only run at 50hz. He is using the 50hz signal as the pulse train. 50htz in a 180step/rev motor means it spins at 180step/rev/50steps/sec=3.6rev/sec or 216rev/min. So if your happy with this speed and this speed only then you can do it this way. You can't use a DC current to run a stepper directly, you need a series of pulses to move it along from magnet to magnet. Cheers Peter S

From Product description:
DC Motor Speed Regulator controls the speed of a DC motor by adjusting PWM.
I thought that if the power was supplied by PWM then the motor would turn.Bob Willson

It will control the speed of a DC motor by PWM, but as it only has two output terminals it won’t operate/control a stepper motor. They need a minimum of 4 output terminals.
