Raspberry Pi 4 Model B 3GB RAM Single-Board Computer

The Raspberry Pi 4 Model B with 3GB RAM marks a significant leap in single-board computing, delivering desktop-class performance in a credit-card sized footprint. Unlike earlier Pi boards, this model integrates a faster quad-core processor, dual-display support, and true Gigabit Ethernet, making it a versatile foundation for everything from media centers to industrial prototyping.

Highlights

• Broadcom BCM2711 quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5 GHz
• 3GB LPDDR4-3200 SDRAM for smooth multitasking
• Dual micro-HDMI ports supporting up to 4Kp60 displays
• 2× USB 3.0 and 2× USB 2.0 ports for high-speed peripherals
• Gigabit Ethernet, dual-band Wi-Fi 5, and Bluetooth 5.0
• 40-pin GPIO header with full backward compatibility

In daily use

Whether you're building a home automation hub, a retro gaming console, or a lightweight desktop, the Pi 4B 3GB handles it with ease. The upgraded USB 3.0 ports allow fast external storage, while the dual micro-HDMI outputs let you run two 4K monitors simultaneously. The improved power delivery via USB-C ensures stable operation even under load, and the board remains passively cooled for typical workloads.
