James, this is just a "dumb" H bridge. You would need a micro (pic or
similar) to provide a PWM signal to drive it.
You would also need the logic necessary to read input in step / dir and
compare to position feedback.
It would not be a good choice for steppers.
Hope this helps.

David

PS the gecko is still one of the best deals around.

Saw this in the Oct 31st issue of EDN magazine. Looks like a neat
little package - supposed to be able to control both servo and steppers.
All in a small package for $30 including nice heatsinks.

www.newmicros.com The product is NMIH-0050

No affiliation with the company, just wanted to share and see everyone's
feedback.

If it looks like a workable solution, I like the price point.

James
