Raspberry Pi 4B Products

Description

The Raspberry Pi 4B Model B (RPi4B) is a credit card sized (3.4in x 2.2in) SBCSingle Board Computer capable of dual HDMI 4K video display, USB peripherals, audio, video, 40-pin GPIOGeneral Purpose Input Output interface, Ethernet, and WiFi/BTBluetooth connectivity. The RPi4B currently comes in three different variants of LPDDRLow-Power Double Data Rate4 SDRAMSynchronous Dynamic Random-Access Memory (2GB, 4GB, and 8GB).

The processing power of the RPi4B consists of a Broadcom 2711 SoCSystem On a Chip with a Quad-Core 64-bit ARM Cortex-A72 CPU at 1.5GHz and VideoCore VI GPU at 500MHz.

The RPi4B Hardware Overview has more details on the board layout, processors, memory, I/O, and power.

Ethernet	1x RJ45RJ45 is the most common type of the connector used for Ethernet networking. RJ stands for “Registered Jack” and 45 refers to the interface standard number. It has eight pins, which means that it contains eight separate wires. Gigabit Ethernet port
Wireless	2.4GHz and 5.0GHz IEEEInstitute of Electrical and Electronics Engineers (Industry Standards) 802.11IEEE 802.11 is a set of protocol standards that define communication for a Wireless Local Area Network (WLAN). In order for WiFi to work between different devices, they all need to agree on how they are going to communicate. The current version of the standard is IEEE 802.11-2007, with many amendments such as 802.11a, 802.11b, 802.11g, and 802.11n.ac WiFi Bluetooth 5.0 & BLEBluetooth Low Energy

Multimedia	H.265H.265 is a video compression standard also referred to High Efficiency Video Coding (HEVC) or MPEG-H Part 2. Designed as a successor to H.264, the H.265 offers from 25% to 50% better data compression at the same level of video quality. (4Kp604K resolution refers to a horizontal display resolution of approximately 4,000 pixels. In television and consumer media, 3840 x 2160 (4K UHD) is the dominant 4K standard. The p stands for progressive scan, i.e. non-interlaced. The 60 stands for 60 frames per second. decode) H.264H.264 is a video compression standard also referred to Advanced Video Coding (AVC) or MPEG-4 Part 10 (1080p601920 x 1080 progressively displayed pixels; also known as Full HD or FHD, and BT.709. 1,920 pixels are displayed across the screen horizontally and 1,080 pixels down the screen vertically.
