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!

Good product, very bad packaging. It arrived with pins bended.

The pins are bent.. Too bad... we need better protection please..

Les broches sont pliés.. dommage... Il faut une meilleure protection s'il vous plaît..

My first order. Loved it. Fast delivery. Track number. I liked the store itself. About the product, unfortunately, I can not say anything, did not check. I place a photo, may be useful to whom.

Мой первый заказ. Понраилось. Быстрая доставка. Трек номер.Сам магазин понравился. О товаре,к сожалению, ничего сказать не могу,не проверял.Размещаю фото,может кому пригодится.

Good product. Well built with a big heatsink. The two modules ordered arrived with bent connection pins. Shipment padding should be better

Happy with previous purchase of 2 units, each unit drives two 37GB555 12V DC motors on a custom vehicle weighing about 5kg, so purchased 2 more units for another vehicle.

The module work great. The application that I am using these for it running drill motors. There are not issues with heat. Very happy so far.

Much awaited. was waiting for a while. Even though the header pins in all the 3 items were bend on arrival ,I think it will work.

as Archimedes said, "Give me a support point and move the world" ...He did not know this monster ( if you have power to supply!!).

Seem good quality, but the packaging was poor. The pins came bent, but it can be fixed.
