If you are going to use a bipolar motor then you need an H-bridge Alex

I am looking 3.3 Volt stepper motor driver circuit because my processor support only 1.8V/3.3V I/O signals. What is the difference between unipolar and bipolar stepper motor? My stepper motor has four input wires only. can I use ULN2803 or ULN2003A? Regards Ashwani Last edited: May 16, 2011
