![]() A nice addition that I found is the aluminium heat sink case from Pimoroni. With this in mind I decided to equip my boards with heatsinks from the very beginning. On my Pi 4 boards right out of the box I’ve seen temperatures rise up to 90 degrees Celsius during CPU-intensive workflows. In most cases it lowers temperature enough to avoid CPU throttling. A simple 15×15 mm passive radiator however is easy to install and does not hurt at all. Since the new chips come with an IHS (integrated heat spreader) you could run them without any type of cooling. The Pi 4 SoC might get pretty hot when put through CPU intensive tasks. ![]() Most modern accessories already employ USB-C ports so cables and adapters should be fairly ubiquitous. The power supply port is now USB-C so you might need a new charger or a micro-B to type-C adapter. You might need micro-HDMI to HDMI adapters or cables to connect one or two external monitors to your Pi 4. This means that most older enclosures might not properly accommodate the new board. Physical differences can be found in the area of Ethernet and USB ports which are now placed in reverse order. I have tested the Raspberry Pi Sense HAT and Camera with the new Pi 4 as well as some older projects with no issues whatsoever. Also the serial display and camera (DSI, CSI) ports are still there. In theory all Raspberry Pi accessories, such as HATs, cameras or displays should work since the 40 pin header is fully backward compatible. Raspberry Pi 4 Model B board with 8 GB RAMīackward compatibility is retained in key aspects.There are now two USB 3.0 ports on-board offering extra bandwidth should it come to need. This means that in theory maximum bandwidth should be attainable. The Gigabit Ethernet interface is no longer sharing bandwidth with the USB ports as it was the case with the Pi 3 B+. The 8 GB version costs almost twice the amount of the 2 GB version. You will need to fork about 35% extra for the top 4 GB variant. Worth emphasizing is that the starting price point for the base Pi 4 configuration is similar to previous versions. The new Pi 4 model B board sports a more powerful Cortex-A72 quad-core SoC with improved graphics while retaining the small form factor that made this development platform famous.īased on memory size there are 1, 2 and even 4 or 8 GB RAM configurations, the latter of which we are taking a look at today. 4-pole 3.5 mm jack for stereo audio and composite videoįor more context you can check out specs for previous iterations such as the Raspberry Pi 3 or even the Pi 2. ![]()
