RioRand DC Smart Car PWM Dual Motor Driver Controller (Module Circuit Board H-Bridge MOSFET IRF3205 3-36V 15A Peak 30A for Arduino)

This would probably work if I knew how to hook it up but the seller doesn't know either.

Good like many have said for low power projects. Mine got fried after hooking it up to a 5 Amp 15V motor. The C5 capacitor caught fire.

I bought one of these for my team's design competition this past year. I was a little concerned about the size of the board, but it fit perfectly in our robot. It does what it says it will. We were able to successfully connect 2 motors to the driver and they worked simultaneously. There was no difference in speed between the motors (I've ran into this problem with other drivers before). Simple assembly and compatible with an Arduino.

I got it working using PWM on arduino. Ramping up the speed, holding a speed for 500 ms, and then ramping down. Great ! Unplugged the arduino and wrote some new code and....nothing. Re loaded old code....nothing. Tested wires for continuity...good...and still nothing. I was excited for 5 minutes and then angry. And bummed. Stick with tried and true products. You get what you pay for. It is obviously cheap for a reason.

Worked great. The mosfets will get hot, but the way they are mounted allows easy addition of a heat sink.

It worked for about 5 seconds and then U5 started to smoke. I am positive the wiring was correct. I tried it with 2 motors at 12V and 5Amp each. Instead I use (2) IBT-2 H-Bridge without problems.

Works perfectly, drive it with an arduino for some good automation projects.

Fried within minutes from running at a 100W motor with a 12V battery. Description says it can handle 15A.
