Raspberry Pi 4 Model B is the latest model released in 2019. It offers ground-breaking increases in processor speed, multimedia performance, memory, and connectivity compared to the prior-generation Raspberry Pi 3 Model B+, while retaining backwards compatibility and similar power consumption. For the end user, Raspberry Pi 4 Model B provides desktop performance comparable to entry-level x86 PC systems. This product’s key features 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. Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz 1GB LPDDR4-2400 SDRAM 2.4 GHz and 5.0 GHz IEEE 802.11b/g/n/ac wireless LAN, Bluetooth 5.0, BLE True gigabit ethernet 2 × USB 3.0 ports, 2 x USB 2.0 Ports Fully backwards compatible 40-pin GPIO header 2 × micro HDMI ports supproting up to 4Kp60 video resolution 2-lane MIPI DSI/CSI ports for camera and display 4-pole stereo audio and composite video port Micro SD card slot for loading operating system and data storage Requires 5.1V, 3A power via USB Type C or GPIO PoE (Power over Ethernet) enabled (requires PoE HAT)
