Description

Raspberry Pi 4 is completely upgraded, re-engineered Faster, more powerful computer from the family of very well know and our most favourite Raspberry Pi Foundation. This is the first time Raspberry Pi is offering a choice of memory capacities.

About Raspberrypi Pi 4 :

  • A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3× performance)
  • 1GB, 2GB, or 4GB of LPDDR4 SDRAM
  • Full-throughput Gigabit Ethernet
  • Dual-band 802.11ac wireless networking
  • Bluetooth 5.0
  • Two USB 3.0 and two USB 2.0 ports
  • Dual monitor support, at resolutions up to 4K
  • VideoCore VI graphics, supporting OpenGL ES 3.x
  • 4Kp60 hardware decode of HEVC video
  • Complete compatibility with earlier Raspberry Pi products

At first glance, the Raspberry Pi 4 board looks very similar to previous products, all the way back to 2014’s Raspberry Pi 1B+. Raspberry Pi Foundation worked hard to keep it this way, but for the first time it has made a small number of essential tweaks to the form factor to accommodate new features.

Power:

Pi 4 has moved from USB micro-B to USB-C for our power connector. This supports an extra 500mA of current, ensuring we have a full 1.2A for downstream USB devices, even under heavy CPU load.

Video:

To accommodate dual display output within the existing board footprint, Pi 4 has replaced the type-A (full-size) HDMI connector with a pair of type-D (micro) HDMI connectors.

Ethernet and USB:

Gigabit Ethernet magjack has moved to the top right of the board, from the bottom right, greatly simplifying PCB routing. The 4-pin Power-over-Ethernet (PoE) connector remains in the same location, so Raspberry Pi 4 remains compatible with the PoE HAT.

The Ethernet controller on the main SoC is connected to an external Broadcom PHY over a dedicated RGMII link, providing full throughput. USB is provided via an external VLI controller, connected over a single PCI Express Gen 2 lane, and providing a total of 4Gbps of bandwidth, shared between the four ports.
