So, the 5V GPIO Pin..

Wed Dec 06, 2017 10:59 pm

I know this is succchhh a newbie question, but I want to be extra safe on this.

I'm guessing the 2 GPIO pins with 5V means that it accepts 5V (such as a fan)

So meaning that if I were to use a 5V mini fan for my Raspberry Pi (for example), it wouldn't burn out the 5V GPIO pin?

I don't want to burn out the pins by accident so I am just asking :P

The 5V pins 2 and 4 are not GPIO. They are connected to the 5V power supply and are always on (cannot be controlled). They can be used to power fans or any other device that requires 5V as long as you don't draw too much power from them.

There are also 2 3V3 pins 1 and 17 which also are full time power.
