This is exactly what I ordered and the shipment was quick. I'll bay from 3D Printing Store again with a smile. Keep up the good work.

One of mine arrived DOA but they replaced it no with no problems, overall very good part, they do get a bit hot so you might want to figure out a way to cool them

Works as expected. Easy swap out on my Prusa i3

I tried fiddling with a UL2003 chip for a while, but the project stalled because of the complexities of reversing the current though the stepper motor. This does it for you! Superb!

I am impressed with the stanility and versability of this driver. It is small in size, but handles the work loads surprisingly well.

I bought this for my REPRAP after burning my previous one. I was surprised to find that this driver was per-assembled as the previous vender I had to solder the parts.
