The Raspberry Pi 4 Model B (3GB RAM) is a compact single-board computer that gives users a memory-density option positioned between the 2GB and 4GB variants, letting you pick the amount of RAM your project actually needs without paying for more than that. Built around the Broadcom BCM2711 quad-core processor, it delivers the same dependable performance, stable connectivity, and consistent output as other Raspberry Pi 4 models.

With 3GB LPDDR4 RAM and the same compact, credit-card-sized form factor, this board is compatible with the full range of Raspberry Pi 4 accessories, HATs, and peripherals 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, media centers, and general-purpose computing and educational projects where a moderate amount of memory is enough.
