Raspberry Pi 4 Model B — 4GB LPDDR4 Single-Board Computer

The Raspberry Pi 4B with 4GB RAM is the workhorse single-board computer for projects that need a real operating system and the performance to run it. Quad-core 64-bit ARM Cortex-A72 at 1.8GHz handles desktop Linux, Python servers, network services, computer vision, and media processing without the constraints of a microcontroller. The 4GB RAM variant accommodates multitasking workloads and memory-hungry applications comfortably.

Dual micro-HDMI outputs support two 4K displays simultaneously. The USB 3.0 ports provide genuine high-speed storage access. Gigabit Ethernet on a dedicated bus (not shared with USB) delivers full-speed network throughput. Runs Raspberry Pi OS, Ubuntu 22.04, and dozens of other ARM64 Linux distributions.
