Whether you’re an engineer, an IoT enthusiast, or a hobbyist looking to create ground-breaking applications we’re certain that you’ll be blown away by the ROCK 3C. This impressive little board is a reliable and extremely capable platform for bringing your ideas to life.
Reliable Rockchip SoC
ROCK 3C provides reliable and capable performance based on the Rockchip RK3566 SoC, Quad core Armv8.2‑A Cortex®‑A55 up to 1.6GHz, Arm Mali™ G52 GPU, and 32-bit LPDDR4 2GB RAM. Rest assured that its compact size doesn’t mean it’s lacking features, the ROCK 3C will deliver outstanding performance while leveraging outstanding mechanical compatibility.
WiFi onboard, as standard
The ROCK 3C benefits from 802.11 b/g/n/ac Wireless LAN support including WiFi5 and Bluetooth 5.0 making it the ideal solution for supporting your IoT applications, whether you’re looking to create a smart application that requires a reliable Bluetooth connection, or you just want to connect your board to the internet via WiFi, the ROCK 3C has you covered!
More OS, more options
ROCK 3C is a super practical little board, as it is compatible with multiple operating systems, including Android 11, Debian/Ubuntu Linux, the full implementation of the Arm architecture v8‑A instructions set, and others.
No more storage limitations
You may think the ROCK 3C lacks storage capacity with its 32-bit LPDDR4 2GB RAM, however, it benefits from a high-speed eMMC socket for eMMC modules which can be used for data storage and OS. The eMMC socket is compatible with readily available industrial pinout and form factor hardware.
Highly compatible with SBC accessories
There’s nothing more frustrating than getting a new piece of tech and finding out it’s not compatible with your existing accessories. The ROCK 3C’s 40-pin header supports a huge range of interface options, offering an abundance of connectivity capabilities meaning the 3C is compatible with almost every accessory you could think of! On top of that, the dual functionality of many of the pins opens the possibilities for advanced accessories, the sky is the limit!
Supports 1080p display
With an Arm Mali™ G52 graphics processing unit (GPU) at its heart, the ROCK 3C is ideal for multimedia applications, such as videos, and signage. The board benefits from camera and display interfaces, HDMI 2.0 port supporting display up to 1080p resolution, near-CD-quality audio output through a 4-ring 3.5mm audio jack with mic input, and more.
