Raspberry Pi 3 B Fan Pins

Using this approach the fan will run all the time i think it is much more i.

Raspberry pi 3 b fan pins. Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. Although overall applications of pi are less it is most preferred when developing advanced applications.

This gpio pinout is an interactive reference to the raspberry pi gpio pins and a guide to the raspberry pi s gpio interfaces. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. Raspberry pi 2 raspberry pi 1 raspberry pi zero raspberry pi 2 b. Where raspberry pi 3 is used.

The raspberry pi 3 model b board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio pins. The raspberry pi has two i2c connections at gpio 2 and 3 sda and scl are for i2c0 master and physical pins 27 and 28 are i2c pins that enable the pi to talk to compatible hat hardware. Control a cooling fan on a raspberry pi 3. The raspberry pi gpio pinout guide.

Intel galileo intel edison esp32 arduino due. 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. Pins 1 2 39 40 are also labeled below j8 pinout 40 pin header. The older iterations of the rpi such as the raspberry pi model b will only contain a total of 26pins.

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.
