Raspberry pi 4 gpio pin layout. 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. Raspberry pi pins description. It also includes dozens of pinouts for raspberry pi add on boards hats and phats.

Raspberry pi 4 pinout. Raspberry pi 2 3 pin mappings. The raspberry pi 4 can be used in the external embedded system to communicate. It has a total of 40 pins from which 28 are gpio pins and the rest of them are power pins.

A powerful feature of the raspberry pi is the row of gpio general purpose input output pins along the top edge of the board. 2x 5v power pins. Support pinout xyz on patreon. Here is the raspberry pi 4 default gpio pinout for the 40 pin j8 header.

A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. This is the configuration of the pins as you ll receive it when you first boot up raspbian or noobs with raspbian. It s the 40 pins you can see on the raspberry pi near the edge. The raspberry pi has 40 gpio pins that connect to sensors lights motors and other devices.

Not only is the raspberry pi 4 bursting with new hardware features but under the hood there are some extra gpio functions to make life a bit easier allowing users to expand their peripherals to their projects without requiring additional hardware in particular there are a bunch of extra i2c uart and spi interfaces that can be used on the raspberry pi 4. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board. You can work out all the other pins from there. Now let s discuss pin layout.

Gpio pins don t only perform the simple i o functions. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. In many ways the raspberry pi 4 improves upon the features set by the pi models before it. The pins description is same for all models.

2x 3 3v. Click the image for an enlarged version. Raspberry pi gpio layout pi 1 model b revision 1 the pin marked p1 is pin 1 and provides 3 3v 50ma max. 1x serial uarts rpi3 only includes mini uart 2x spi bus.

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. 1x i2c bus.
