Raspberry Pi 4 Model B, 4GB is a compact single-board computer for building projects, learning programming or running a small Linux-based system. It pairs a Broadcom BCM2711 quad-core 64-bit processor with 4GB of memory.
For connecting peripherals and add-on electronics, the board provides two USB 3.0 ports, two USB 2.0 ports and a 40-pin GPIO header. Two micro-HDMI outputs support displays up to 4Kp60, while a microSD slot holds the operating system and data.
Networking is built in, with dual-band Wi-Fi, Bluetooth 5.0 and Gigabit Ethernet. This mix of interfaces makes the board suitable for desktop-style use as well as programmable projects that connect sensors, displays or other peripherals.
