DOES NOT WORK! I've 12v going Im, and 12v going out. Wired up to the top comments photo. The output from the mosfet is VERY weak and my 12v LED is very dim. Tried shuffling wires to no avail.3 out of 5 don't work with ardino so RIP my led project. Some of these don't quite allow all of the voltage to go through with a 5v signal.

This is a nice little driver board. I really like the layout, led and connectors. However, the FET choice isn't the best to be driven by a 3.3V control signal. There are tons of better options. I recommend poking around on DigiKey for a better FET for your application

I like the gate LED. They work good and I have no real complaints but, I wish it was a mixed bag of n-type and p-type and there is a resistor on board that I wish I could easily change (see me whining). Most people will not want this. I got what they said it was but not whirled peas.I see many comments and complaints about the same thing in one form or another. So here's the thing, coils bite! you can get ten times the voltage you think you can when you turn a coil OFF. (like in a motor or relay) . This is physics! And Amazon does not yet carry products that violate natural law.So these should not be used with Arduino without diode protection! and then a transistor. Of course if you're not driving over 9V you don't need these anyway. Then you will have a 9V or more, rail to work with. Then you can use an NPN transistor (almost any will do) with a pull up resistor and you're good to go. This method will work and it will prevent releasing the boards magic smoke. And I'm sure many little Arduino lives have been saved by this not working directly at 3.3V.

The specs say it'll work with 3.3v, but don't expect these to be reliable at that level. I'm running a 12v input, the logic pin opens the gate, the red LED comes on, but when a load is attached on the output, the voltage is zero. When there isn't a load, it has 12v on the output rail.I'll keep them for lower power uses (like 5v devices), but a little disappointed they're not working with my 12v.

I've bought these more than once for hobbyist projects. It works great to allow you to control a higher power device. In one application, I used this to power a 12V relay. The Arduino can't provide 12V so I used this to control the relay. The relay then switched 120V AC to turn on and off a pool pump. This device can only go up to 24V DC which is why I needed the relay to switch AC power. If you connect this to a relay, consider adding a flyback diode for protection (google that for more information). In another application, I used this to control a large 5V LED sign. It was 5V but required about 900mA of current. The Arduino can't provide that much power, so this device allows for that (assuming you hook up a power supply in purple with enough capability). The attached image depicts these connections. I made this to explain it to my kids who helped me wire this up. The other review with the schematic was incredibly useful to me as an engineer, but I made this to make it more straightforward for an 11 and 12 year old. Overall a good device. My pool pump application has been working for 2 years and I'm hoping this light controller will have similar success.
