hi KeBul,
Here's an example.

The power/earth pins are not GPIO's. They are fixed at 5V, 3.3V or 0V
and can't be turned on and off.
The GPIO's can be turned off and on but don't have much current capacity
so extra circuitry is usually required. Usually a transistor and a
resistor or 2. This solution will typically have 3 con

Hmmm, n
Remember when connecting devices directly to GPIO's you need to keep in
mind the current draw.
The power and earth pins have higher current capacity than the GPIO's.
Normally for motors, you would connect a transistor to the GPIO that
switches the power to the motor.

Hi,
Just tested this for you.
I used GPIO 17 which is Pin #11 on the 40 way header
31581
31582
I set up pCP gpio-poweroff as follows:
31580
When pCP is up and running I have 3.3v on Pin #11 (GPIO17)
When I shutdown pCP I have 0v on Pin #11 (GPIO17)
Not sure if this is what you are after,
I've not played around with these at all but from a quick read up on RPi
GPIO's I think Pin #1 is fixed 3.3v
You need to use a configurable GPIO pin, try Pin #17, set as an output,
set to high will give you 3.3v on that pin, set to low will give you 0v
on that pin.
Can't see how to set a pin as
I have a Fan on my Rpi Model #4 that I am trying to turn off and on
using the GPIO Switches on the Tweaks Page.
The Fan is Hooked to Pin #6 - Ground and Pin #1 - 3.3 volts
I have tried to shut it off using gpio-poweroff, but have not
succeeded.
I set it to pin #1 and rebooted, but the Fan was st
