Rock Pi 4 Model C+ (4GB) Single Board Computer
Next-Gen Power and Dual-Display Versatility for Makers and Developers
The Radxa Rock Pi 4 Model C+ is a high-performance single-board computer (SBC) engineered to meet the demands of modern developers, IoT innovators, and tech hobbyists. Powered by the robust Rockchip RK3399-T hexa-core processor utilizing ARM's big.LITTLE architecture, this board seamlessly manages resource allocation across two high-performance Cortex-A72 cores and four energy-efficient Cortex-A53 cores. Backed by 4GB of high-speed 64-bit dual-channel LPDDR4 RAM and a specialized Mali-T860MP4 GPU, it delivers desktop-class responsiveness, making it a premier alternative to traditional single-board platforms.
Designed with versatility in mind, the Model C+ boasts exceptional multimedia and expansion capabilities. It sets itself apart with dual micro-HDMI outputs that support simultaneous dual-display setups—ideal for digital signage, multi-monitor workstations, and immersive 4K media streaming. Additionally, the integration of a dedicated eMMC socket and an on-board M.2 connector provides lightning-fast storage upgrades that bypass the historical bottlenecks of MicroSD cards. Complete with an integrated on/off power button for safe system shutdowns and a highly compatible 40-pin GPIO header, the Rock Pi 4 Model C+ represents a rugged, future-proof platform for your most ambitious tech builds.
