Re: Stepper motor driver

ULN will work fine if you are using unipolar motor.
If you are going to use a bipolar motor then you need an H-bridge

Re: Stepper motor driver

Sorry for first post. 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
