Raspberry Pi 3 B Gpio Layout
Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes.
Raspberry pi 3 b gpio layout. Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats. If you re an owner of a raspberry pi b 2 zero or 3 then you will have 40 pins in total. 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. If you love pinout please help me fund new features and improvements.
See below for the raspberry pi gpio pinout diagram. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board. The raspberry pi gpio pinout guide. Click the image for an enlarged version.
2x 5v power pins. Raspberry pi gpio layout model b one of the most significant changes to the raspberry pi model b is the 40 pin header j8. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. Raspberry pi 3 model b gpio 40 pin block poe header pinout.
You can work out all the other pins from there. Explaining the raspberry pi gpio pinout ref. 1x serial uarts rpi3 only includes mini uart 2x spi bus. Raspberry pi gpio layout pi 1 model b revision 1 the pin marked p1 is pin 1 and provides 3 3v 50ma max.
This gpio pinout is an interactive reference to the raspberry pi gpio pins and a guide to the raspberry pi s gpio interfaces. This is the configuration of the pins as you ll receive it when you first boot up raspbian or noobs with raspbian. The earlier models such as the raspberry pi b have just 26 pins. The older iterations of the rpi such as the raspberry pi model b will only contain a total of 26pins.
We have included all three iterations of the pi for the pinout diagram. 5 minutes to read. This offers and increase of 14 pins over the 26 pin header on the original raspberry pi. Here is the raspberry pi 4 default gpio pinout for the 40 pin j8 header.
24x gpio pins. 2x 3 3v.
