5PCS DC 5V-36V 15A(Max 30A) 400W Dual High-Power MOSFET Trigger Switch Drive Module 0-20KHz PWM Adjustment Electronic Switch Control Board Motor Speed Control Lamp Brightness Control

These are very reliable and run at a low temperature. I've been using them to control 4-pin fans and blowers (though 3-pin would work fine with these modules) for a wind simulation setup, and these PWM controllers have run continuously at 12V for days without any problems. I haven't bothered with heatsinks or cooling fans; passive airflow in an enclosure has been adequate. Screw terminals make it easy to install your source and drain wiring. The 10-pack is a good bulk price for tinkerers and hobbyists.

Used this as part of a college final project where we needed to control a solenoid with an arduino. This made it possible.

I combined this with TTP223 touch modules to switch 12V LED lighting strips in my kitchen. Works great! My installation also includes a 12V power supply to power the LEDs and a 5V buck regulator to power the touch modules.Like others have mentioned, this product is only good for resistive loads. It is not designed to run motors.

Of course the first one I ever used had one defective MOSFET that always passed full current. If it wasn't the first one I would not have wasted so much time trying to figure out why NONE of my control circuits were working.Note To Self: New = Untested SuspectThe others were fine, and I even figured out which MOSFET was bad on the first one and cut the leads (now it's a 15amp module I guess) Otherwise, works as advertised!

Work as expected. Value for money

Works for inductive loads like motors only if you modify it. As shipped, it is unsuitable for inductive loads.I wanted to control a 7A motor with one of these, using an Arduino R4 to control it. That can be done, but this is what I did to make it work: 1. Add a flyback diode. 2. Cut the leads to one of the two MOSFETs. 3. Add a heat sink. 4. Add a reverse voltage protection diode so that in the event of a catastrophic failure the Arduino does not get fried (yes--I had such a failure). Optional: I added a 100uF capacitor across the input. (For convenience I also added a female header on the trigger pins.) Note that this device switches ground and that trigger ground is shared with the controlled ground. This might be a problem for some users.With all of this, it works quite well in my application controlling a 7A motor with 12kHz PWM from an Arduino R4. But, should I really have to do all of this? Why does it not come with a flyback diode? And if there are going to be two MOSFETs, why not put in a control circuit designed for two MOSFETs.

Using it to control a train set frome home assistant. Works great

First off, I see no issue with the soldering. Each component is correctly soldered on in the correct place. Second, yes, ground is switched, as you can see on the backside. This module allowed me to take the pwm signal from an ESP32 and make it work for 12V white LED lights using WLED. Easy to connect, very straight forward. 10/10
