I brought home 7 motor driver boards, of which 2 already worked. The other 5 were completely dead, after a few hours I de soldered the mosfets and tested them with a multimeter. I found out the same 2 mosfets were dead on each motherboard, so I was only able to repair 3 of the 5 boards I had because I didn't have enough mosfets for all the boards. After the mosfets were replaced, the boards worked perfectly, some needed a little bit of tweaking but they worked!
