Raspberry Pi 4 Model B Gpio Pinout

The older iterations of the rpi such as the raspberry pi model b will only contain a total of 26pins.
Raspberry pi 4 model b gpio pinout. Raspberry pi gpio layout model b. One of the most significant changes to the raspberry pi model b is the 40 pin header j8. This is the configuration of the pins as you ll receive it when you first boot up raspbian or noobs with raspbian. If you orient your pi such that you are looking at the top with the gpio on the right and hdmi port s on the left your orientation will match pinout.
This guide has been updated to reflect the. Pinout depicts pin 1 in the top left corner. Here is the raspberry pi 4 default gpio pinout for the 40 pin j8 header. Pin 1 is the only pin with a square solder pad which may only be visible from the underside of your pi.
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. Every pi model since the raspberry pi b has had 40 gpio pins though on the pi zero and zero w you have 40 holes that you can solder pins or wires into. Any of the designated gpio pins can be used either as a input output pin with a wide variety of applications suitable. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header.
By matt on july 18 2014 model b. 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. This offers and increase of 14 pins over the 26 pin header on the original raspberry pi. Raspberry pi 4 pinout.
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. Raspberry pi b gpio header details and pinout 14. In many ways the raspberry pi 4 improves upon the features set by the pi models before it. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes.
