I like the concept of this board. And I gave the highest stars for all things related to this item. This is of the only ones out there with a convenient " toggle " switch " for reversing the direction of DC-motor . As soon as my board arrived ( late ) I tried to test it's range. Provided the supply current of 12V/1A from a wall-wart paying attention to hot and ground wires and matching to the input port of the board. A green LED indicator went high all good. Connected a 12v/0.8A geared motor to the output of the board. set the Pot at it's lowest. Set the toggle to one side ( don't remember which side ) another LED indicator went High on the output side. Here starts the bad:
I was looking at the motor on the bench while increasing the load on the motor. At this point I wasn't even passed the halfway on the Pot that the magic smoke started coming out of a few components of the board. By the time I killed the power it was too late.
Well, perhaps I got the only bad unit. Back to the Banggood for buying another one. Good thing these bangs are really inexpensive.
