Raspberry Pi 3 B Fan Pins

Control a cooling fan on a raspberry pi 3.

Raspberry pi 3 b fan pins. Gpio header power pins. The header provides 5v on pin 2 and 3 3v on pin 1. The comprehensive gpio pinout guide for the raspberry pi. This gpio pinout is designed to be both a quick and interactive reference to the raspberry pi gpio pins plus a comprehensive guide to your raspberry pi s gpio interfaces.

Using this approach the fan will run all the time i think it is much more. Support pinout xyz on patreon. In order to avoid damaging your pi you need to be sure what pins you are connecting to other hardware and that your program is referring to the correct pins. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w.

Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. The 3 3v supply is limited to 50ma. Pi hardware raspberry pi 1 model b model b io pins note that we are not currently sure if the new pin 27 40 pwm1 gpclk1 and gpclk2 peripheral pin functions will be made accessible under raspbian and if so which pins they will be assigned to hence the duplicated pins shown with these functions.

The pi 3 b was the first model i used a fan with for intensive computing e g. Running a kubernetes cluster but it could be used for light computing fanless. If you re using the raspberry pi b 2 zero 3 or the latest raspberry pi 4 model b you ll discover that your board have a total of 40 gpio pins. Cooling your raspberry pi keep performance constant and drops temperature significantly.

How to install raspberry pi fan for raspberry pi 2 and 3 model b. The older iterations of the rpi such as the raspberry pi model b will only contain a total of 26pins.
