HiLetgo BTS7960 43A Dual H-Bridge Stepper Motor Drive Current Limit Control Semiconductor Refrigeration PWM for Smart Car Motor Drive for Arduino

Very handy module to have at a great price. I had some trouble trying to use mine, but I think the problem was with my attached circuitry. The first one I bought is now happily running and the spare waiting for something big to drive (I've checked it works). Having the current sense pins of the drivers available is a nice bonus although I didn't try to use it.Like some other reviews, my first module had one of the driver chips dodgily attached, with a couple of its pins very close together. Easily solved but potentially catastrophic, so check yours over before use. Both modules also arrived with the control headers a little bent as they're shipped in nothing but an anti-static bag. Again easy to fix but also easily remedied by the supplier with a cardboard box.

appalling solder quality as can be seen from the image - doesn't work as a result

The heat sink shorted the board rendering the unit unusable..

DOA.
