Raspberry Pi 4 Gpio Pin Map

A powerful feature of the raspberry pi is the row of gpio general purpose input output pins along the top edge of the board.

Raspberry pi 4 gpio pin map. Mapping pin di raspberry pi 2 3 raspberry pi 2 3 pin mappings. Raspberry pi 2 3 pin mappings. 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. To confuse things even more the gpio pins are sometimes renamed with another set of numbers.

In order to avoid damaging your pi you need to be sure what pins you are connecting to other hardware and that your program is referring to the correct pins. 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. It is powered by an arm cpu a broadcom. 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.

The comprehensive gpio pinout guide for the raspberry pi. Raspberry pi latest model 4b comes with an ethernet connector wifi bluetooth hdmi output usb connectors a 40 pin gpio and other essential features. Raspberry pi 1 models a and b have only the first 26 pins. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header.

A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. This gpio pinout is designed to be both a quick and interactive reference to the raspberry pi gpio pins plus a comprehensive guide to your raspberry pi s gpio interfaces. 2x 5v power pins. Support pinout xyz on patreon.

2x 3 3v. Every pi model since the raspberry pi b has had 40 gpio pins. Gpio header power pins. 24x gpio pins.

Instead a new serial port dev ttys0 has been provided which is implemented with a software based uart miniuart. 1x serial uarts rpi3 only includes mini uart 2x spi bus. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board. Le interfacce hardware per raspberry pi 2 e raspberry pi 3 vengono esposte tramite l intestazione 40 pin j8 sulla lavagna.

5 minutes to read. 4 minuti per la lettura. The header provides 5v on pin 2 and 3 3v on pin 1. 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 has 40 gpio pins that connect to sensors lights motors and other devices. Here s a map and detailed explanation of what each does including on the pi 4.
