Tudo Ok
Works good in cnc board with nema17 steppers
All Ok, all on right.
3 pieces as desired All is well
For the prize you get reliable drivers in which you can configure the limit current. The heatsink is only needed if you use half steps or smaller ones. Buy more than you need since it is possible one of them came defective.
One of my CNC drivers fails and I replace it with this one. Good quality
works well, expected results. thanks!

The device is described, with the exact specifications. Tested with a NEMA 17.
