Raspberry Pi 4B: A small and powerful microcomputer

Short Description:

product description
It is a microcomputer motherboard based on ARM, using SD/MicroSD card as the memory hard disk. There are 1/2/4 USB interfaces and a 10/100 Ethernet interface around the card motherboard (type A does not have a network port), which can be connected Keyboard, mouse and network cable, as well as a TV output interface for video analog signals and an HDMI high-definition video output interface. The above components are all integrated on a motherboard that is only slightly larger than a credit card. It has all the basic functions of a PC and only needs to be connected to the TV. and keyboard, you can perform many functions such as spreadsheets, word processing, playing games, playing high-definition videos, and more. Raspberry Pi B model only provides a computer board, no memory power supply, keyboard, chassis or connections.

Key features of Raspberry Pi 4B:
Faster processing speed:
1. The latest Broadcom 2711 quad-core Cortex A72 (ARM V8-A) 64-bit SoC processor clocked at 1.5GHz improves power consumption; and thermals on the Pi 4+B mean that the CPU on the BCM2837 SoC can now run at 1.5 GHz That’s a 20% improvement over the previous Pi 3 model, which ran at 1.2GHz.
2. Video performance on Pi 4 B has been upgraded with dual monitor support at resolutions up to 4K via a pair of ports; hardware video decoding up to 4Kp60, support for H 265 decoding (4kp 60); H.264 and MPEG-4 decoding (1080p60 ).

Faster wireless:
1. Compared to the previous Pi 3 model, a significant change in the Pi 4 B is the inclusion of a new, faster; dual-band wireless chip that supports 802.11 b/g/n/ac wireless LAN.
2. Dual-band 2.4GHz and 5GHz wireless LAN supports faster network connections with less interference, and new PCB antenna technology supports better reception.
3. The latest 5.0 allows you to use a wireless keyboard/trackpad with more range than before, without extra dongles; keeps things tidy.

Enhanced Ethernet connectivity:
1. The Pi 4 B has significantly faster wired networking, with USB 3.0 technology; thanks to the upgraded USB/LAN chip; you should see speeds up to 10 times faster than previous Pi models.
2. The GPIO header remains the same, 40 pins; fully backwards compatible with previous motherboards, such as the first three models of Pi. However; it should be noted that new PoE plugs may come into contact with components on the underside of certain caps; such as rainbow caps.
