I have a feeling I'm not unable to do this but I would still rather ask the more knowledgeable folks just in case I'm either wrong or you happen to have an alternative suggestion.
I have my RP4 on a case with a miniature 5V cooling fan and I want to add this fan controller so I can control the fan speeds. However, I would also like to add a tiny screen such as the Adafruit PiOLED but as far as I understand these pins are already taken by the fan.
Am I correct? In that case, are there any other simple ways around adding this or something similar?
Thanks in advance for the help.
So I moved the fan to the 3.3V GPIO pin 17 and Ground pin 20 and it still works albeit at a lower speed, which is great. However, I've tried to add
dtoverlay=gpio-fan,temp=60000 to the
config.txt expecting a on/off situation but it seems to remain always on, even after updating, upgrading and rebooting.
I would be happy settling with the fan only triggering when reaching the previously defined 60C as I've already managed to free the pins to add the PiOLED.
The PiOLED seems to use the GPIO pins 1-6 but this 5V Controllable Fan seems to use the GPIO pins 4, 6 and 8. When checking Pinout, it looks like I could possibly keep the UART TX on pin 8, move GND to pin 9 and the 5V to 3.3V on pin 17. This would be on less power but I would be ok with that as long as it's not an issue.
Would this be ok or is this train of thought incorrect?
