NEW Rock Pi 4 Model C+ 4GB SBCin the original, factory sealed box.Why is it "Better Alternative to Raspberry Pi 4 Model B 4GB"?The Rock Pi is a single board computer with slightly higher specs than the Raspberry Pi, and comes with the added benefit of being able to run Android. At its heart, the Rock Pi runs on an ARM-based processor known as the Rockchip. The Rockchip features theArm big.LITTLE technology with 6 cores. It is aDual Cortex-A72@1.5GHz and a Quad Cortex-A53@1.0GHz CPU. It has more cores, more interfaces, and more storage solutions. It is the same size as its competitor, the Raspberry Pi 4B, and will mechanically work with most Raspberry Pi 4B accessories.Best of all, it is more affordable.
Key benefits of the ROCK 4C+ single board computerReliable Rockchip SoC
ROCK 4C+ provides reliable and robust performance based on the Rockchip RK3399-T SoC, Arm big.LITTLE technology Dual Cortex-A72@1.5GHz, Quad Cortex-A53@1.0GHz CPU, Arm Mali – T860MP4 GPU and 4GB 64bit LPDDR4 RAM. Be sure that your board will deliver outstanding performance, it’s solid as a ROCK!
Overclocking
The SoC is the Rockchip RK3399T, which has six cores.Two of them are Cortex-A72, the kind found in the Raspberry Pi 4, which run by default at 1.5 GHz. They can, of course, be overclocked to 2 GHz. The remaining four cores are Cortex-A53, seen in Amazon Fire tablets and the Nintendo Switch. These run at 1 GHz but can be overclocked to 1.5 GHz.
Power On/Off button
You ask, and we listen. FINALLY, a board with a built-in On/Off power button that can now perform safe shutdowns at the touch of a button without the risk of corrupting storage. ROCK 4C+ is an energy-efficient single-board computer that offers this huge convenience compared to alternative boards, allowing you to be flexible with your applications.
More OS, more optionsROCK 4C+ is extremely practical, as it is compatible with multiple operating systems, including Android, Debian/Ubuntu Linux, the full implementation of the Arm architecture v8‑A instructions set, and others.
No more storage limitations
ROCK 4C+ benefits from extensive storage capacity, including 4GB RAM and a high-speed eMMC socket for eMMC modules which can be used for OS and data storage.
Highly compatible with SBC accessories
The 40-pin header supports a wide range of interface options, providing the board with a vast range of connectivity capabilities to ensure exceptional compatibility with a wide range of existing accessories. Due to the dual functionality of many of the pins, the ROCK 4C+ opens the possibilities for advanced accessories never seen before!
Dual monitor 4K output
With an Arm Mali T860MP4 graphics processing unit (GPU) at its heart, the ROCK 4C+ is perfect for advanced multimedia applications, including games, videos and signage. The board benefits from camera and display interfaces, two micro HDMI ports supporting dual displays up to2Kp60 and4Kp60 resolution, high-quality stereo audio output through a 3.5mm audio jack, and much more.
True thermal management
The ROCK 4C+ has a 2pin 1.25mm header, allowing the connection to a 5V fan (or other peripheral), which can be PWM controlled.
Who is Radxa?
OKdo has an exclusive partnership with Radxa to manufacture and distribute ROCK Single Board Computers (SBCs) and ROCK System on Modules (SoMs). Radxa is a technical startup founded in 2013 that focuses on the design, manufacture and production of open-source hardware products that include the range formerly known as Rock Pi.
