Raspberry Pi Foundation has finally made some encouraging adjustments to the Raspberry Pi Model B product line. Since the introduction of Raspberry Pi 1 Model B+, the company took nearly 6 years to finally release an SBC that is capable of supporting some desktop features.

Raspberry Pi 4 is different from its predecessors because it supports spreadsheet juggling, drafting of presentations, editing documents, and opening multiple tabs for convenient browsing. Raspberry Pi 4 Model B has the standard Raspberry Pi SBC size. The form factor is different in terms of positioning of some components and the replacement of a few interfaces. It is suitable for all Raspberry Pi users who want to enjoy the desktop-like experience on a Single Board Computer. Raspberry Pi 4 is low-cost and energy-efficient in comparison to a desktop.

Raspberry Pi 4B Drawing 

A bird’s eye view doesn’t notice all the adjustments Raspberry Pi Foundation has made to make Raspberry Pi 4 a reliable upgrade. If you focus on the form factor, you will realize that there are some significant upgrades to Raspberry Pi 4 Model B that are not available on any other Raspberry Pi SBC so far.

Efficient Power Consumption

Previous Raspberry Pi models had a Micro-B port to receive power supply but Raspberry Pi 4 has USB-C. Due to this upgrade, 1.2A is supplied to the downstream USB devices because USB-C manages to supply the additional 500mA. So, the power doesn’t fluctuate even if the processor is dealing with a heavy load.

Type-D Micro HDMI

Raspberry Pi 4 features a couple of Type-D Micro HDMI connectors instead of the full-size HDMI (Type-A) you get with the earlier Raspberry Pi SBCs.

Compatible with the PoE HAT

The previous Raspberry Pi models had the Ethernet at the bottom-right but Raspberry Pi 4 Model B has the Gigabit Ethernet Magjack at the top-right. This adjustment makes PCB routing simple. The position of the PoE connector remains the same and this is because Raspberry Pi 4 requires PoE HAT to support Power over Ethernet.

4Gbps Bandwidth for USB Ports

The Express Gen 2-Lane Single PCI facilitates 4x USB interfaces (External VLI controller support) with a total of 4Gbps bandwidth.
