I've used the SMD N channel MOSFET with numerous different arduino projects, to PWM things up to a couple amps. The chip is rated at 5.8amps. But I've always used it with a 5 volt PCB.
This project is a 3.3V board, but I'm assuming it will work ok? I've always had the gate of the MOSFET connected directly to the a digital pin, as per recommendation found here on the forum. Will the 3.3volt work to properly turn on the gate as the 5 volt did?
(I'll be using PWM from the digital pin, to control a 12 volt DC fan that draws about 500mA max.
thanks.
I've added PDF files of my schematic and layout. The PCB is a Thermocouple/fan controller shield for a Wemos D1 Mini PRO.
