Video & sound: 2 × micro HDMI ports (up to 4Kp60 supported), 2-lane MIPI DSI display port, 2-lane MIPI CSI camera port, 4-pole stereo audio and composite video port.

GPIO: Standard 40-pin GPIO header (fully backwards-compatible with previous boards).LAN, Bluetooth 5.0, BLE Gigabit Ethernet, 2 × USB 3.0 ports, 2 × USB 2.0 ports.Connectivity: 2.4 GHz and 5.0 GHz IEEE 802.11b/g/n/ac wireless.Memory: 2GB, 4GB or 8GB LPDDR4 (depending on model).Processor: Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC 1.5GHz.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. 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, up to 8GB 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). For the end user, Raspberry Pi 4 Model B provides desktop performance comparable to entry-level x86 PC systems.

Raspberry Pi 4 Model B 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.
