Decent controller but it needs immediate work to make it safe! There is zero electrical isolation between the heat sink and the through holes under the driver IC's, its relying purely on the anodised layer on the heatsink, if the two IC's make contact though the heatsink you will have a short and potentially when there is massive current flowing through them! Place a 0.5 or 1mm thick silicone thermal pad over the though holes on each output and it will make it safe, the heatsink needs them anyway as its just a bare heatsink as shipped. If you only going to be running it at low current, say 10 amp Max or less, you can just take the heatsink off but you must not leave it as it comes shipped, its a fire waiting to happen!

BG374211144 Can you please share a picture of the installation of the silicone pad. I ordered 8 of them and want to make sure they can be used safely

LeVonn I wish more people were like you. Thanks for the helpful and even lifesaving tip. Chinasium never cares.

BG573216380 I'vereceived two, and am thinking of putting Kapton tape over the pcb, leaving the through holes area to fill with heatsink compound.
