Raspberry Pi 4 Specifications Pin Diagram and Description

Raspberry Pi 4 Model B is one of the recent Raspberry Pi single-board computers. In this blog, you will see Raspberry pi 4 specifications Pin Diagram and Description. You can do all kinds of basic tasks using this computer what you need one monitor, keyboard and mouse. you can play low graphics games, stream 4k video connecting on two displays, all your office work, and many more.

This small computer is designed for learning purposes. It was made for those who can’t afford expensive computer hardware but still want to learn. The performance of this small computer is similar to entry-level x86 based pc systems.

Raspberry pi runs a Debian-based operating system known as Raspbian (Raspberry Pi OS). It is officially provided by the Raspberry Pi foundation.

Raspberry Pi 4 specifications include:

  • It has a 64bit quad-core processor having cortex-A72 (ARM v8) clocked @1.5GHz.
  • The new Pi board includes Broadcom BCM2711 VC6 GPU able to handle two 4kp30 displays also it can handle H.265 decoding at 4kp60. It has two micro HDMI ports.
  • Now the new Pi board comes in 2GB, 4GB, and 8GB LPDDR-4 RAM options.
  • It has a dual-band 2.4/5.0 GHz Wi-Fi, Bluetooth 5.0, Gigabit Ethernet Port, 2 USB 3.0, and 2 USB 2.0 ports.
  • USB type C power input port. Also, it has POE capability via separate POE HAT (add-on).
  • It has a standard 40 pin GPIO header (having backward compatibility)

The new Raspberry Pi is even more fast, powerful and versatile for a huge variety of projects involving robotics, automation, image processing, AI, and many more.

Let’s take a closer look at Raspberry Pi:

The Processor of Raspberry Pi 4 :

Pi has a more powerful quad-core Cortex-A72 64-bit CPU running at 1.5GHz and Broadcom VideoCore VI GPU running at 0.5GHz. It can handle 4k videos, H.265 encoding 2 HDMI outputs. It has a fully functional Gigabit Ethernet interface and USB 3.0 port.

  • Software-driven router
  • Media server
  • A bridge between Wi-Fi and Ethernet networks

USB Controller :

VL805 chip is the USB port controller for Raspberry Pi 4. The Pi has 2 x USB 3.0 and 2 x USB 2.0 ports.  VL805 chip is a USB 3.0 Host controller. it allows the PCI Express platform to interface with USB Super-Speed (5 Gbps), High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) devices. The root hub is consists of four downstream facing ports, it enables simultaneous operation of multiple peripheral devices.

Power Circuitry :

The Pi4 uses the MXL7704 it was developed specifically for Raspberry. This chip reduced the complexity of the Pi board and also delivers more power to all the peripheral to run at more power. Due to this chip cost of the board has also been reduced as the number of components has been reduced.
