Raspberry Pi Gpio Pin Layout

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

Raspberry pi gpio pin layout. 1x serial uarts rpi3 only includes mini uart 2x spi bus. Not only does the single board computer support more ram a faster processor speed and expanded peripherals but the gpio pins retain their standard functions set by previous models along with extra functions for existing pins. In many ways the raspberry pi 4 improves upon the features set by the pi models before it. This is the configuration of the pins as you ll receive it when you first boot up raspbian or noobs with raspbian.

Click the image for an enlarged version. 2x 5v power pins. Raspberry pi 40 pin gpio layout if you are reading the raspberry pi copyright statement printed on the pcb then pin 1 is in the bottom left and pin 40 is in the top right. This offers and increase of 14 pins over the 26 pin header on the original raspberry pi.

Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. The majority of raspberry pi models use the same 40 pin header. 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. The comprehensive gpio pinout guide for the raspberry pi.

Support pinout xyz on patreon. The raspberry pi has 40 gpio pins that connect to sensors lights motors and other devices. Raspberry pi gpio layout model b one of the most significant changes to the raspberry pi model b is the 40 pin header j8. It also includes dozens of pinouts for raspberry pi add on boards hats and phats.

A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. 1x i2c bus. 5 minutes to read. 2x 3 3v.

Raspberry pi 2 3 pin mappings. Here s a map and detailed explanation of what each does including on the pi 4. Here is the raspberry pi 4 default gpio pinout for the 40 pin j8 header. The goal of the gpio pins is to add some extensions to your raspberry pi for example most of the raspberry pi hats use these pins to connect with the raspberry pi you can also create your electronic circuit by using these gpio pins with cables led and other accessories.
