I had previously purchased a different type of motor controller and experienced a lot of frustration getting that to work. I bought this which was possibly overkill spec wise for my project but everything worked exactly as expected which was a big relief.I connected this up to a single RS390 dc motor for testing and then connected a couple different RS390 dc motors that are connected to an electric assist cart. This was part of a fun project to control the motors with a raspberry pi and a bluetooth controller for remote control. I originally powered the controller with the raspberry pi through the 5v pins for testing/software setup then removed those and connected it up to a 12v power source (lithium ion battery) and in both instances, it worked just fine and as expected. No issues for me with the screw terminals or pins luckily.I may need to troubleshoot further with my software implementation but I am having issues with maintaining power to the motors when I apply "max" power. Right now they're cutting out at full power which should be limited to 98% of max but I could have that configured wrong.Definitely great for various projects and has me interested in seeing what else I can do with them.

I'm happy with this driver so far and I will update this review if it breaks. I'm only giving 3 stars because I feel the manufacturer should have taken the 30 minutes to write basic instructions. Luckily for me at least one of the other reviews has really good info that has already saved me from destroying the electronics. With that in mind I can add a little more info:I'm using channel A for the left side motor and channel B for the right side. I'm using IN1 for forward-PWM and IN2 for reverse PWM. The way the motor break works is that if you reduce the speed (lower PWM duty cycle) while the EN pin is high, the motor will almost instantly switch to the lower speed and cause a voltage spike on the power rail. In my testing I saw double the input voltage, so this would probably be bad for the battery and other electronics. What I recommend instead is set EN to low first before reducing the speed via PWM signal which would let the motor decelerate in a free-spin. Then time it to set EN back to high once the speed has naturally reduced. There are other ways to solve this but just so you know that going from a high speed to a low speed while EN stays active may break things.When stopping the motor, set speed to 0 while EN is high to stop instantly (voltage spike does not seem to happen in this case) or set speed to 0 after setting EN to low to let the motor free-spin to a stop.I would also be careful about changing direction. I would bring the motor to a stop first then accelerate in other direction. Like I said, would have been nice to have some proper instructions.

Le circuit fonctionne très bien, MAIS le V+ (pin côté controlleur) et PWR+ (côté moteur) sont COMMUNS ! Si vous utilisez un arduino, ne branchez pas le V+ au arduino, car si vous utilisez par exemple 12V pour les moteurs, 12V iraient directement dans le arduino. Le mien a brûlé de cette manière !

Would be nice if there was instructions for what each thing means. However it isn't overly difficult to find whe look up from arduino to output to double h bridge. Different then others that ground is only in pins but that is not an issue for myself but may be one for others.Pins labeled for a or b motor nicely. Only tested with low voltage. If issues at 12v will update but so far very happy with the item****Update.***** As can see in pictures at 12v it did not hold up. I believe this is a manufacturing flaw and not the norm. Will order a replacement after return is completed as sometimes the connections have weak points and believe that was the case here and not the typical result nor is the failure on the seller.Sadly Amazon did not give me an option to ontat seller directly about this so return was the only option. Looking forward to the replacement and will update once I have been able to connect the new one into the system I need it for.Update*New one received seller is good to deal with, only seems to allow fully on or full off. Pwm isn't working with it.

I bought this awhile ago, spent forever trying to find documentation on it, wired it up, and instantly cooked it, my arduino, and a wire. After more digging, I discovered that it was my own fault for connecting v+ to the 5v on the arduino. (Turns out it’s electrically identical to the main power supply.) After ordering another one and hooking it up correctly, I can confidently say that it’s amazing. However a lack of clear documentation makes it virtually impossible to use without trial and error that may fry the system. Fortunately, those reading this review can learn from my mistakes, and hopefully get some good use out of this amazing controller.- The three v+ pins (A, B, and the V+ next to the motor output) are electrically identical. This means that you should only power one of them. Not recognizing this may fry pretty much everything connected.- The ground pins are also electrically identical. However, in this case, the control circuitry (ie arduino) must be connected to the ground pins for the PWM signal to work.- EN must be set to high (ie powered by 5v) for the motor to operate. If using an arduino, wire this up to any digital output. It also plays a role in a coasting/braking feature, but I’ve never used it as such. I just turn it off when the speed is zero.- IN1 and IN2 are for forward and reverse PWM signals, and should be wired up to two PWM pins on an arduino. While one is receiving a PWM signal, the other should always be set to low. Never give these pins more than 98% PWM. If using an arduino with 8-bit PWM, that means a maximum value of 250.- CT is not necessary for motor function. It is an output pin, and if wired up to analog in on an arduino, will give you the current for each motor. I’ve never actually used it, so I have no idea what math is used to calculate it.If you keep these facts in mind when wiring and programming, it’s an amazing motor controller that I would absolutely recommend.

Terrible! Absolutely impossible to find a guide on how to use this garbage. Waste of my money!
