Great product. I drove it from a PIC 18F26K22. No problems driving the stepper although if I pushed the speed to quick it didn't move (yeah expected) so watch out for that. Thanks for a nice product and quick shipping.
Really nice design. Unfortunately mine came with a defective motor. The Rengineer would have been more than happy to replace it for me, but I just bought a whole batch from eBay instead. I do recommend this board absolutely.
This cool little motor has delicate leads which are arranged with some really odd spacing. This board makes mounting the motor into a project or enclosure a snap. I'm also impressed it includes the diodes which are often overlooked in other projects, but (IMHO) required in any good design.
Well done! Recommended.
