Orange pi 4B GPIO problem

AlbNieOPi

Hello.

I have a problem with my Orange pi 4B, I did try to plug a fan using the 4 and 6 pines but it did not worked, when I did check the curret I´d see that it was 0v in all the GPIO, so I have not current there.

Is there any solution for this? Thank you.

Hello.
In order to use GPIO you can install OPi.GPIO Libraries. If you are using debian or ubuntu images for the OPi4/4B the instructions are very straightforward:
1.

1. cd /usr/local/sbin/OPi.GPIO/

Copy code

2.

1. sudo pip install .

Copy code

3.

1. pip3 install .

Copy code

4.

1. sudo python test_gpio.py 11

Copy code

(to test pin 11, blinking a led)

Then, you can connect a fan through a transistor for pulling current from power pins, or attatch to 5.0V pin and GND (Pin 4 and 6 respectively)
