Introduction

Raspberry PI4 Pinout is the latest version of the Raspberry Pi series of single-board computers. It was released in June 2019, and since then, it has been used for various projects, including robotics, home automation, and media centers. One of the essential features of Raspberry Pi 4 is its GPIO (General Purpose Input/Output) header. The GPIO header consists of 40 pins, which are used for interfacing with external devices and components. In this blog post, we will discuss the Raspberry Pi 4 pinout and its uses.

The Raspberry Pi 4 Pinout

The Raspberry Pi 4 Pinout Model B has a 40-pin GPIO header, which is used for general-purpose input/output (GPIO) and to interface with various external devices and components. The GPIO pins are numbered from 1 to 40, and they are grouped into four categories: Power pins, Ground pins, UART pins, and SPI pins.

• Power Pins: The power pins on the Raspberry Pi 4 are used to provide 3.3V and 5V power to external devices and components. The power pins include 3.3V Power, 5V Power, and 3.3V Power.
• Ground Pins: The ground pins on the Raspberry Pi 4 are used to provide a common ground for external devices and components. The ground pins include Ground, Ground, Ground, and Ground.
• UART Pins: The UART (Universal Asynchronous Receiver/Transmitter) pins on the Raspberry Pi 4 are used for serial communication. The UART pins include TXD (UART), RXD (UART), and Ground.
• SPI Pins: The SPI (Serial Peripheral Interface) pins on the Raspberry Pi 4 are used for interfacing with SPI devices. The SPI pins include MOSI (SPI), MISO (SPI), SCLK (SPI), CE0 (SPI), CE1 (SPI), and Ground.
• I2C Pins: The I2C (Inter-Integrated Circuit) pins on the Raspberry Pi 4 are used for interfacing with I2C devices. The I2C pins include SDA1 (I2C), SCL1 (I2C), SDA0 (I2C), and SCL0 (I2C).
• GPIO Pins: The GPIO pins on the Raspberry Pi 4 are used for general-purpose input/output. The GPIO pins include GPIO 0, GPIO 1, GPIO 2, GPIO 3, GPIO 4, GPIO 5, GPIO 6, GPIO 7, GPIO 21, GPIO 22, GPIO 23, GPIO 24, GPIO 25, GPIO 26, GPIO 27, GPIO 28, and GPIO 29.
