10PCS DC 5V-36V 15A(Max 30A) 400W Dual High-Power MOS Transistor Driving Controller Module FET Trigger Switch Drive Board 0-20KHz PWM Electronic Switch Control Board DC Motor Speed Controller

These have been my go to boards for a couple years for high power and fast switching applications. They are so cheap for what they can do. I usually add a header to the board to plug into another board (like Arduino). I've had a couple fail over the years, but it could have been my fault. These are good for 15A (30A max), that's quite a bit of power. The only part I don't care too much for are the screw terminals, I never feel like they grab the wires really well, when I actually have never had a wire pull out (must be good then).

I just wish they included a flyback diode across the load, but other than that these work great. The flexible signal pad layout is clever.Note that you can convert these to be breadboard friendly-ish by desoldering the connectors and cutting off the positive Vin and Vout section and half of the signal connector. There's probably better dedicated breadboard options but this worked for me.

The item is powerful and compact. It is easy to use.

This is a great, inexpensive N Channel MOSFET breakout board. It's not much more than that. The board includes a pair of MOSFETs in parallel, but has no load leveling resistors, flyback diodes or any isolation for the input. The input saturates from 3V up to 10V, with a lower on resistance with the higher the trigger input voltage. With a high Vin voltage and a low trigger voltage, the MOSFET may require cooling such as the heat sinks that are glued to DRAM chips.The D4184 MOSFETs have a maximum Vin of 40V and a maximum gate voltage of 20V. Going over 12V on the gate, however, will greatly reduce the life of the gate LED. Each D4184 supports 5A continuous current draw with no cooling, and 40A continuous current draw with cooling. They can also handle 150A pulses as long as the diode junction temperature does not exceed 170C. The maximum theoretical square wave frequency is 7Mhz under ideal conditions. I've tested a couple boards up to 200khz (my application's maximum frequency) and they work fine.If you plan on using these to drive a heavy load from 3.3V or 5V, I would highly recommend using a MOSFET driver chip, or just a lower power logic level MOSFET, and drive the gate to 12V. I've included a schematic of the board for anyone interested. Also, give the large quantity of boards included, if you want a terminal block for the trigger input, just salvage it off another board. That's what I've done.

I am disappointed there wasn’t any documention, i.e. Schematics and specifications coming with the product.. I could only find a schematic left in the feedback from another user, and pin out in the thumbnails on the Amazon site.
