12V Fan on PI GPIO

Sat May 26, 2018 9:18 pm

I have a 12V 0.10A Fan (Brushless DC) lying around and I would like to use it on my Raspberry Pi 3B. Would it be possible to run it at its max RPM but not destroy the Pi, keeping in mind that I have a few LEDs hooked up and will be hooking up other things too.

Any help would be appreciated

You will need an external 12V supply as the pi does not have 12V on it, you will also need a transistor and resistor to allow the 3.3V of the gpio to control the 12V

If you search the forum you will find several posts about this very subject.
