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 options

ROCK 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 to 2Kp60 and 4Kp60 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.
