Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header.

Raspberry pi 3 b gpio map. This offers and increase of 14 pins over the 26 pin header on the original raspberry pi. Raspberry pi 2 3 pin mappings. However i m not sure which set of pins i should plug the fan into. The ground pins on the raspberry pi are all electrically connected so it doesn t matter which one you use if you re wiring up a voltage supply.

I am currently installing the pi into a super tinytendo case which came with a built in mini fan. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. Makes working with it much easier. 2x 3 3v.

24x gpio pins. On the raspberry pi model 3b the hardware based serial uart device dev ttyama0 has been re purposed to communicate with the the built in bluetooth modem and is no longer mapped to the serial rx tx pins on the gpio header. 1x i2c bus. 5 minutes to read.

The raspberry pi has 40 gpio pins that connect to sensors lights motors and other devices. Raspberry pi 40 pin gpio header. The raspberry pi gpio pinout guide. I have a raspberry pi 3 model b.

Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats. The leaf shows the original broadcom numbered gpios. The majority of raspberry pi models use the same 40 pin header.

Generally the one that s most convenient or closest to the rest of your connections is tidier and easier or alternatively the one closest to the supply pin that you use. Here s a map and detailed explanation of what each does including on the pi 4. Instead a new serial port dev ttys0 has been provided which is implemented with a software based uart miniuart. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board.

3 3v on 2 pins 5v on 2 pins ground on 8 pins general purpose input and output. Raspberry pi b pinout leaf. It has two pin holes with red and black cables. Pwm pulse width modulation i2c.

If you love pinout please help me fund new features and improvements. These allow a massive range of sensors motors leds and accessories to be connected to the pi. 2x 5v power pins. 1x serial uarts rpi3 only includes mini uart 2x spi bus.

According to the specs the mini fan is 5 volts. Inspired by the original rasperry leaf but for the 40 pins of a raspberry b.
