Very bad product. Enable pin does not work. Voltage level not pull high enough for RST and Sleep pins looped together.

Installed one of these in my Bachin Chinese laser engraver. Although the old chip was not a fault, this one was a direct replacement and I have left it in. I bought these because of near-unanimous positive feedback. They are a great product, and I will buy again should the need arise.

Fixed my laser machine that wouldn't go to the right.

Works great for playing around with stepper motors. They do get pretty hot and the kit includes metal heatsinks and double-sided tape. You could also use a single device to control a couple of DC motors.

Plugs right in the the Arduino board and works

Of the three I got, the first one I tried didn't trigger the Nema17 I use for testing -at all-. I swapped it out for a second one and the tests ran fine. When it started acting up days later I swapped it out for the third and found that I had to twiddle the timing of the high and low triggers to the step pin because the timing that worked on #2 didn't work on #3 and it kept locking up the motor. These things are cheaply, but maybe they're made TOO cheaply. Will gladly pay more for reliable, dependable quality.
