This is a rather nice Stepper motor controller.
This is a rather nice Stepper motor controller. You can change speed and direction, single step or turn a pre-determined number of full turns.
Output is to either the printer port or the user port. There is no help file at the moment, but the controls are fairly obvious. I have included a PCB negative. I can send the board at near cost, but you have to supply your own stepper motor.
