Raspberry Pi 4

The Raspberry Pi 4 Model B is a powerful, fourth-generation Single-Board Computer (SBC) featuring a 1.8GHz quad-core Cortex-A72 CPU, up to 8GB LPDDR4 RAM, dual 4K micro-HDMI ports, and true Gigabit Ethernet.

This is the Raspberry Pi 4 Model B: a significant performance leap over its predecessors, offering desktop-class computing in a credit-card-sized form factor. It is driven by the Broadcom BCM2711 chip (Quad-core Cortex-A72 @ 1.8GHz) and supports up to 8GB of LPDDR4 RAM, making it roughly three times faster than the 3B+ model. Key connectivity upgrades include two USB 3.0 ports, two micro-HDMI ports supporting dual-display 4K output, and full Gigabit Ethernet. Use it as a cost-effective desktop replacement, a powerful media center (4Kp60 decode), or the core controller for advanced robotics and IoT projects via its standard 40-pin GPIO header.
