So, be really careful when you plug something or when you create a test circuit. If you connect a ground (GND) pin to a 3.3V pin directly, well… You might destroy your Raspberry Pi board the second those pins are connected together. There are no real hardware safety when it comes to the Raspberry Pi hardware pins. A word of cautionīefore you plug anything to a Raspberry Pi 4 pin, you have to know that you can easily damage the board if you do something wrong. Now, let’s break down each pin or group of pins, and see what they can do. Here’s a complete overview with all the GPIOs and their primary function. The difference between Raspberry Pi 4 pins and Arduino pins.Communication protocols through Raspberry Pi 4 pins.You are learning how to use Raspberry Pi to build your own projects?Ĭheck out Raspberry Pi For Beginners and learn step by step.Īfter watching the video, subscribe to the Robotics Back-End Youtube channel so you don’t miss the next tutorials! > Watch this video as an additional resource to this article: If you’re interested about Arduino pins, check out this tutorial: Arduino Uno Pinout Guide. At the end I’ll give you more details about the differences between Arduino and Raspberry Pi pins.

You’ll find out that the pins can be quite similar for some functionalities. In this complete Raspberry Pi 4 pins guide I’ll break down all the pins of the GPIO header, and you’ll learn what you can/can’t do with them.Īlong the way I’ll make some comparisons with the pins of the Arduino boards. It brings the Raspberry Pi 4 much closer to hardware applications, making it perfect for being embedded in a hardware application or product: a robot, a retro-gaming application, etc.

GPIOs allow you to easily use hardware features and communication, directly from a computer – the Raspberry Pi microprocessor. This GPIO header is also the same for Raspberry Pi 3 boards, so this guide applies to both versions. The Raspberry Pi 4 board has a GPIO header with 40 pins.
