Raspberry Pi 4 B Pins

I2c or the inter integrated circuit protocol allows your raspberry pi to control multiple sensors and components known as slaves.

Raspberry pi 4 b pins. Below is a brief description of each. All power out pins are given below. Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats. Raspberry pi model 4b has 40 gpio pins in total stacked in 20 x 2 array.

Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. The raspberry pi 4 has undergone extensive compliance testing and meets a number of regional and international standards. Here is the raspberry pi 4 default gpio pinout for the 40 pin j8 header. As shown in the below diagram each pin has a specific purpose.

The raspberry pi gpio pinout guide. For the first time we ve built a complete desktop experience. The speed and performance of the new raspberry pi 4 is a step up from earlier models. This guide has been updated to reflect the.

View and download relevant certificates and conformity documents. Whether you re editing documents browsing the web with a bunch of tabs open juggling spreadsheets or drafting a presentation you ll find the experience smooth and very recognisable but on a. The pi 4 has expanded the capability of many pins by supporting these interfaces on more of them than the raspberry pi 3b before it. 5v is directly connected to the usb port but 3v3 is connected to through the regulator which gives the stable 3 volts output.

Click the image for an enlarged version. Every pi model since the raspberry pi b has had 40 gpio pins though on the pi zero and zero w you have 40 holes that you can solder pins or wires into. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. There are two types of power output pin in the raspberry pi 4 3v3 and 5v.

The raspberry pi 4 model b pi4b is the first of a new generation of raspberry pi computers supporting more ram and with siginficantly enhanced cpu gpu and i o performance. This is the configuration of the pins as you ll receive it when you first boot up raspbian or noobs with raspbian. The power input pin of the raspberry pi 4 is given below. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes.
