Temp is the minimum temperature in millicelsius at which the gpio pin activates default 55000.
Raspberry pi 3 fan gpio.
The raspberry pi gpio pinout guide.
Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header.
Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats.
Place in your case or even better on top of your pi s cpu to give it extra air flow.
The fan should receive power automatically when the pi is booted.
I purchased a pi fan came in a 2 pack from amazon since it fits nicely above the board and comes with the proper screws for mounting.
Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes.
A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w.
If you love pinout please help me fund new features and improvements.
