Raspberry Pi 4 Model B Gpio Pinout

In many ways the raspberry pi 4 improves upon the features set by the pi models before it.

Raspberry pi 4 model b gpio pinout. Rev 1 pi alternate bcm numbers for the original 26 pin model a and b pi. This offers and increase of 14 pins over the 26 pin header on the original raspberry pi. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. The raspberry pi model b board revision 2 0 contains both a 26 pin expansion header labeled as p1 providing access to 17 gpio pins and an 8 pin expansion header labeled as p5 providing an additional 4 gpio pins for a total of 21 gpio pins.

Raspberry pi b gpio header details and pinout 14. 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. As shown in the below diagram each pin has a specific purpose. The raspberry pi 3 model b board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio pins.

By matt on july 18 2014 model b. Feel free to print embed share or hotlink this image and don t forget to credit us. 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. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes.
