LGDehome 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

Powered module up with 24vdc (two 12v batteries @ 15A each) to control a 250W-24v dc motor, connected to a twist throttle, and an arduino. Yeah, it works alright when I give a full twist and safely return it but magically blows up (or shorts somewhere) when I try to twist throttle for another revv. I used 3 different modules and they kept blowing up in the same way. I've just ordered some cutoff diodes to prevent back emfs, or so i'm thinking. I'll give updates later.Update:(Mar. 2) - I gave 1 star initially but I've updated to 5 stars after testing module with cut-off (or flyback) diodes. It works great on the 250W scooter!

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).

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.

Used these to PWM control aftermarket 14 inch 90W radiator fans with arduino nano. No heatsinks. Used PWM library to get rid of noise, change frequency. At>1000Hz or higher they start heating up. Have to get over 10KHz to eliminate noise. Ran motor at under 200Hz and they never heat up. Perform well and noise is less than engine noise. All I want! Final build will have heatsinks even though it doesn't need them.I'm ordering more for stock!

The PCBA assembly is high quality, the circuit works fine, and they're capable of driving a decent amount of amps while staying cool. Unfortunately, the screw terminals selected here are a deal-breaker.The terminals are pretty low-quality; in almost 1/4 of the boards, one or more screws were jammed and wouldn't turn at all, meaning I had about a 25% scrap rate on these parts. On the ones that functioned, though, they're too small and too janky. I had trouble getting a 16 AWG stranded wire to fit under the clamp at all, they don't hold with a lot of force so vibration can knock them loose, and they really require a perfectly horizontal wire entry so doing wiring work while these are mounted in any sort of enclosure where access is from above is incredibly challenging.

These work perfect with 3.3V logic pin. Would like to be able to get board without screw headers but that's not mfg fault. Great device!

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.
