Review on HiLetgo Controller Stepper H Bridge Mega2560 by John Mejia

All the devices on this board appeared to be placed and soldered in an automated process, so they're pretty solid. On the other hand, the motor driver and heatsink combo is what I expected from this price point: terrible. On 3/4 of these boards I could put the panda between the motor driver and its heatsink, which of course means it does next to nothing. On the 4th the driver leaned until it touched the edge of the heatsink but still not perfect. If you run *every* board I received at full rated power, it will overheat. 5-10 minutes refinement of each board to accept and turn on. I wouldn't buy this if I didn't have a good soldering station.
