The Raspberry Pi 4 Model B (4GB RAM) is a compact single-board computer built for users who need more headroom for multitasking, development, and slightly heavier workloads compared to the base 2GB variant. Powered by the Broadcom BCM2711 quad-core processor, it delivers dependable performance, stable connectivity, and consistent output for computing, learning, and embedded projects.

With 4GB LPDDR4 RAM and the same compact, credit-card-sized form factor, this board comfortably handles multiple running applications, browser tabs, and lightweight servers, while remaining compatible with a wide range of accessories and HATs through its standard 40-pin GPIO header. Its dual-band wireless and Gigabit Ethernet support stable networking, while dual micro-HDMI output enables smooth dual 4K display use for multimedia, digital signage, and multitasking.

The board runs on a 5V/3A USB Type-C power supply and boots from a microSD card loaded with Raspberry Pi OS or another supported distro. It is well suited for programming, IoT development, robotics, home automation, home servers, media centers, and general-purpose computing projects that need a bit more memory than entry-level boards.
