The Raspberry Pi needs no special introduction. The new RPI 4 Model B is the latest and greatest Pi produced yet and by far the most popular ARM computer. The new RPI-4 offers ground-breaking increases in processor speed, improved multimedia performance, more memory, and faster connectivity older Raspberry Pi 3 Model B+ models. When running as a headless web server, the Raspberry Pi 4 Model B provides comparable performance that can compete with entry-level x86 PC systems. This is largely due to key features that include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K via a pair of micro-HDMI ports, hardware video decode at up to 4Kp60, 4GB of RAM, dual-band 2. 4/5. 0 GHz wireless LAN, Bluetooth 5. 0, Gigabit Ethernet, USB 3. 0, and PoE capability (via a separate PoE HAT add-on). The dual-band wireless LAN and Bluetooth have modular compliance certification, allowing the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market.
