Hi all,
I think I might have damaged the fan power.
Preparing a Noctua 5v fan, I stupidly inverted the positive and negative wires, and now not even the fan that came with the kit is spinning when connected to the board fan connector.
If I take the 5v power from a USB port, both fan spin.

I am currently running Armbian and I have unsuccessfully tried the code below suggested by @yaazzz I've got from another post.

Code: Select all

echo 59 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio59/direction
echo 1 > /sys/class/gpio/gpio59/value



With a tester, I checked the voltage from the connector pins and without load, I got 5v, but as soon a fan is connected, the voltage drops to 2.5v

I've also tried, unsuccessfully, to start from scratch, flashing an official image.
None of the images I've flashed, aside the one from Armbian, has booted from the SD.


Any suggestions?
Did I fry part of the board?

Thank you.
