The Raspberry Pi 4 Model B has landed and it’s quite a big upgrade from the 3B+ .

Earlier this year, rumors said that it would take some time before a major upgrade and I wasn’t expecting it this year, yet here it is :) .

The new version offers a better CPU, more RAM, dual HDMI outputs, better USB and Ethernet performance.

There are currently three varietes of the Raspberry Pi 4: one with 1GB of RAM, one with 2GB of RAM and one with 4GB of RAM available for £34, £44 and £54, respectively.

Technical Specifications:

  • 1.5GHz 64-bit quad-core ARM Cortex-A72 CPU ( ARM v8, BCM2711B0)
  • 1GB, 2GB or 4GB RAM (LPDDR4)
  • On-board wireless LAN - dual-band 802.11 b/g/n/ac
  • On-board Bluetooth 5.0, low-energy (BLE)
  • 2x USB 3.0 ports, 2x USB 2.0 ports
  • Gigabit ethernet
  • Power-over-Ethernet (requires additional Raspberry Pi PoE HAT)
  • 40-pin GPIO header
  • 2× micro-HDMI ports (up to 4Kp60 supported)
  • H.265 (4Kp60 decode)
  • H.264 (1080p60 decode, 1080p30 encode)
  • OpenGL ES, 3.0 graphics
  • DSI display port, CSI camera port
  • Combined 3.5mm analog audio and composite video jack
  • Micro-SD card slot
  • USB-C power

Web serving is one of the most popular use cases for the Raspberry Pi. The Pi 4 promises even more robust web developing / deploying thanks to its faster processor, greater amount of RAM and better network connectivity, in fact I will upgrade the current setup (Raspberry Pi 3B+) and deploy an NGINX web server on the Raspberry Pi 4 paired with the just released Raspbian Buster Lite OS.
