regpye 24/12/2017

The board does not work and gets very hot when powered up. By disconnecting the motor power the board will somewhat work, but not power the motors. Something has been designed wrong, maybe in the motor driver section. No further instructions available and I have bought two of these and the first one is no good. Also there is no indication on where a laser should be connected, no instructions provided for anything except what is printed on the board itself. No jumpers supplied for the M1, M2 and M3 connections of the motor drivers. Very disappointed with this product.
