Raspberry Pi 3 B Gpio Pins Diagram

The b offers 9 extra gpio pins which can be configured as inputs of outputs.

Raspberry pi 3 b gpio pins diagram. This is the configuration of the pins as you ll receive it when you first boot up raspbian or noobs with raspbian. Raspberry pi 1 models a and b pi 2 model b pi 3 models a b and b pi 4 and pi zero zero w and zero wh gpio j8 have a 40 pin pinout. This brings the total number to 26 17 9. Raspberry pi 1 models a and b have only the first 26 pins.

Here is a diagram showing all 40 pins. Last modified by christopher stanton on jun 18 2019 11 47 am. 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. Here is the raspberry pi 4 default gpio pinout for the 40 pin j8 header.

Pins 1 2 39 40 are also labeled below j8 pinout 40 pin header. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. 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. Instead a new serial port dev ttys0 has been provided which is implemented with a software based uart miniuart.

Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats. The raspberry pi model b board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio 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. Raspberry pi pinout diagram circuit notes how to navigate your raspeberry pi 3 model b if you build it they will program.

The raspberry pi gpio pinout guide. If you love pinout please help me fund new features and improvements. Raspberry pi 3 model b. This gpio pinout is an interactive reference to the raspberry pi gpio pins and a guide to the raspberry pi s gpio interfaces.

A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. In the pi zero and zero w the 40 gpio pins are unpopulated having the through holes exposed for soldering instead. On the raspberry pi model 3b the hardware based serial uart device dev ttyama0 has been re purposed to communicate with the the built in bluetooth modem and is no longer mapped to the serial rx tx pins on the gpio header.

Newer computers and game consoles have replaced the old machines where most of us learned to program. The extended header offers an additional 3 ground pins.
