Bi-Polar Stepper Motor Driver Reviews:

  • --> This is a serious motor driver. The kit assembled easily, and it can be used with current source or ballast supplies giving excellent performance. 5 volt control signals from a computer parallel port work well. I built 2 of them for a prototype, and it looks like I will just use these kits instead of custom designing anything if I go to production.
