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.
