Raspberry Pi 3 B Gpio Pin Diagram

1x serial uarts rpi3 only includes mini uart 2x spi bus.

Raspberry pi 3 b gpio pin diagram. Here is the raspberry pi 4 default gpio pinout for the 40 pin j8 header. If you re an owner of a raspberry pi b 2 zero or 3 then you will have 40 pins in total. This is the configuration of the pins as you ll receive it when you first boot up raspbian or noobs with raspbian. This gpio pinout is an interactive reference to the raspberry pi gpio pins and a guide to the raspberry pi s gpio interfaces.

The genesis of the raspberry pi came from a few college students concerned about the dwindling number and skills of students applying to study computer science. 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. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. Click the image for an enlarged version.

24x gpio pins. Raspberry pi 3 model b. Raspberry pi 2 3 pin mappings. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes.

If you love pinout please help me fund new features and improvements. Raspberry pi pinout diagram circuit notes how to navigate your raspeberry pi 3 model b if you build it they will program. Pi hardware raspberry pi 1 model b model b io pins note that we are not currently sure if the new pin 27 40 pwm1 gpclk1 and gpclk2 peripheral pin functions will be made accessible under raspbian and if so which pins they will be assigned to hence the duplicated pins shown with these functions. 2x 3 3v.

1x i2c bus. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. The earlier models such as the raspberry pi b have just 26 pins. Raspberry pi 3 model b gpio 40 pin block poe header pinout version 5 created by christopher stanton on mar 8 2018 12 53 pm.

See below for the raspberry pi gpio pinout diagram. The b offers 9 extra gpio pins which can be configured as inputs of outputs. We have included all three iterations of the pi for the pinout diagram. Explaining the raspberry pi gpio pinout ref.

Newer computers and game consoles have replaced the old machines where most of us learned to program. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board. The extended header offers an additional 3 ground pins. 2x 5v power pins.

The older iterations of the rpi such as the raspberry pi model b will only contain a total of 26pins. Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats. Last modified by christopher stanton on jun 18 2019 11 47 am. So that s a total of 8.

Here is a diagram showing all 40 pins. Click to view larger image.
