5PCS DC 5V-36V 15A 400W Dual MOSFET Trigger Switch Drive Module

Clearly marked circuit pathways and a good fully functional gating system with your ground being common and your positives isolated. Have fun.

I use these to control some fountain water pumps and for that application they work well. I can adjust the pump to set the water flow as desired. But while these are really good and work well, there is no way they are going to handle 15 amps without a fan and a heatsink.

Anyone doing hobby or prototype work must have these handy.

Works well as a solenoid driver. One star for crap screw terminals. I removed them and soldered directly to the board. Also be sure to add a good flyback diode to inductive loads like solenoids.

I love these because you don't even need a microprocessor. If you like to do things in your car - this is a perfect replacement for a relay. And so easy to use. The item in the image could easily control 12V with a very small voltage (like 3.3v and say a 220ohm resistor). I've used it successfully with an ESP32 PWM configuration. Great stuff. My pic shows one connected to a standard 12v adapter. Don't forget to use a flyback diode if controlling things with coils (or any inductive reactance). The only diode I see on the board is an LED that goes on when the circuit is closed (flowing - input energized)

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

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.

Work as expected. Value for money
