Raspberry Pi 4 Model B 4GB

The Raspberry Pi 4 Model B 4GB delivers significant increases in processor speed, multimedia performance, memory, and connectivity while retaining backwards compatibility and similar power consumption to prior-generation boards. As a single-board computer, the Raspberry Pi 4 Model B provides desktop performance comparable to entry-level x86 PC systems, making it suitable for a wide range of projects from learning and development to desktop use and media playback. Key features include a high-performance 64-bit quad-core processor and up to 4GB of RAM on this model, enabling improved multitasking and application responsiveness. The board supports dual-display output via two Micro HDMI ports with resolutions up to 4K and hardware video decoding at up to 4Kp60 for smooth high-resolution media playback. Connectivity options include dual-band 2.4/5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet for fast wired networking, and USB 3.0 for high-speed peripheral connections. The board also offers Power over Ethernet (PoE) capability when used with compatible accessories. Because the Raspberry Pi 4 has higher power requirements than previous models, it requires a 3.0A USB-C power supply (sold separately). If you already own a MicroUSB power supply rated at 3.0A, you may use a microUSB-to-USB-C adapter to power this board. Note that the standard HDMI connector used on earlier Raspberry Pi boards has been replaced by two Micro HDMI ports on the Raspberry Pi 4, so a 4K60P Micro HDMI-to-HDMI cable is required for 4K output and two such cables are needed for dual-monitor operation. This Model B 4GB variant provides an excellent balance of memory and performance for users who need more headroom for multitasking, media, and development projects while maintaining the compact, versatile form factor of the Raspberry Pi platform.
