Product Description
The Rock Pi 4 Model B is an advanced single-board computer (SBC) developed by Radxa, powered by the Rockchip RK3399 hexa‑core processor—a combination of two high-performance Cortex‑A72 cores and four energy-efficient Cortex‑A53 cores. Graphics are handled by a Mali‑T860MP4 GPU with support across various APIs like OpenGL ES, Vulkan, OpenCL, and even DirectX 11. The board supports multiple storage options, including bootable eMMC, microSD, and high-speed M.2 NVMe SSDs, making it ideal for high-performance applications. With 4K HDMI output, MIPI-DSI/CSI interfaces, and a 40-pin GPIO header, the Rock Pi 4 Model B is highly versatile—perfect for makers, developers, edge computing, media centers, and IoT projects. Its robust design, open-source support, and compatibility with Linux distributions (like Ubuntu and Debian) make it a strong alternative to the Raspberry Pi for users who need more power and flexibility.
