Raspberry Pi 4 Pinout, Specifications, Pin Configuration & Programming

In this article, we will briefly go over the Raspberry Pi 4 Pinout, Specifications, Pin Configuration, and Programming. The Raspberry Pi is a credit card-sized computer that plugs into your TV and a keyboard. It is a low-cost, high-performance computer that is widely used in embedded applications.

The Raspberry Pi 4 has a quad-core 64-bit ARM Cortex-A53 CPU and a Broadcom VideoCore VI GPU. It is the most powerful Raspberry Pi model yet. You can connect the Raspberry Pi 4 to a monitor or TV to use it as a desktop computer. You can also use it to create projects such as a homemade security camera or a media server.

The board also features two USB 3.0 ports, compared to the single USB 2.0 port on the Raspberry Pi 3. One of the most useful features of the Raspberry Pi is its GPIO (general-purpose input/output) header. This 40-pin header allows the board to be connected to a wide variety of external devices, such as sensors, LEDs, and buttons. 

Getting Started with Raspberry Pi 4


The Raspberry Pi 4 is a powerful little computer that can be used for a type of different projects. If you’re thinking about getting started with the Raspberry Pi 4, here are a few things you should know.

Raspberry Pi 4 Pinout

The Raspberry Pi 4 Pinout diagram is a great resource for understanding the Pi 4’s GPIO pins and what they can be used for. The diagram shows the location of the various pins and their functions. It’s a great resource for anyone looking to get the most out of their Raspberry Pi 4.


Raspberry Pi 4 GPIO pin

Raspberry Pi 4 GPIO pins are the physical interface between the Raspberry Pi 4 and external hardware. They provide a means of communication between the Raspberry Pi 4 and external hardware. The Raspberry Pi 4 GPIO pins provide a means of communication between the Raspberry Pi 4 and external hardware.

Raspberry Pi GPIO Pins Configuration

Raspberry Pi 4 GPIO Pins are 40-pin female header pins that provide access to Raspberry Pi’s General Purpose Input/Output interface. They can be used to receive input from external devices or to control output to external devices. GPIO pins can be used to control LEDs, motors, and other devices.

Some pins have specific functionality, in addition to being able to be used as simple inputs or outputs. You can see them in the following table:

PWM – Software: All pins
– Hardware: GPIO12, GPIO13, GPIO18, GPIO19
– SPI1: MOSI (GPIO20); MISO (GPIO19); SCLK(GPIO21); CE0 (GPIO18); CE1 (GPIO17); CE2 (GPIO16)
I2C  Data (GPIO2); Clock (GPIO3)
– EEPROM: Data (GPIO0); Clock(GPIO1)


Orientate your Pi with the GPIO on the right and the HDMI port(s) on the left.

  • GPIO (General Purpose IO)
  • SPI (Serial Peripheral Interface)
  • I2(Inter-integrated Circuit)
  • UART (Universal Asynchronous Receiver/Transmitter)
  • PCM (Pulse Code Modulation)
  • Ground
  • 5v (Power)
  • 3.3v (Power)

You can also configure a GPIO pin for a special function, such as I2C, SPI, or UART. These functions allow you to communicate with other devices using serial protocols.

GPIO (General Purpose IO) – Raspberry Pi GPIO (General Purpose IO) describes the pins on a Raspberry Pi that can be used for digital input and output. The GPIO pins can be used to control devices such as LEDs, motors, and sensors.

SPI (Serial Peripheral Interface)- SPI is a full-duplex serial protocol, meaning data can be sent and received simultaneously.  SPI is a full-duplex serial protocol that can be used for communication with flash memory, sensors, real-time clocks (RTCs), analogue-to-digital converters, and more.

I2C – (Inter-Integrated Circuit) – The I2C pin is a pin that can be used to communicate with I2C devices. The I2C bus can be used to connect multiple devices, such as sensors, EEPROMs, and other I2C devices.

UART – Universal Asynchronous Receiver/Transmitter – In computing, a universal asynchronous receiver/transmitter (UART /ˈjuːɑːrt/) is a computer hardware device for asynchronous serial communication in which the data format and transmission speeds are configurable.

PCM (Pulse Code Modulation)The PCM interface is a digital interface for connecting audio devices. It is used to convert analog audio signals into digital audio signals.

5v Power – Raspberry Pi 5v power supply is a great way to get started with powering your own projects. The power supply provides 5 volts of power and is compatible with all versions of the Raspberry Pi.

3.3V Power – All Raspberry Pi models since the B+ can provide up to 500mA on the 3v3 pins.
