Great little drivers

They were genuine Pololu drivers and lived up the reputation. They are well made and have been solid performers. There is a large ground plane on these boards in the inner layers that acts as a heat sink. Be sure to solder the ground pins well when you install the headers. I consider myself quite proficient at soldering and still ended up with a cold joint on one of them since the ground plane drained the heat so quickly but hey, that is what it is supposed to do. Have a small non-conductive jeweler's screwdriver handy, the tiny SMT pots for current control are hard to adjust any other way. That is by no fault of the manufacturer, it's just part of the price to be paid making these awesome boards so small.
