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.
Key benefits of the ROCK 3C single board computer
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 1GB 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 1GB 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.

How to realize a servo and water sensor function using simple raw materials.

With the Earth’s population still on track to increase by another two billion people by the year 2050, finding ways to feed them without causing grave harm to the environment is a top priority. Currently, fish is one of the most widely consumed foods in the world, and a new technology called biofloc helps provide both a food source and environmental stabilizer to fishponds without the need for dangerous chemicals/processes. As part of element14’s Just Encase Design Challenge, Md. Khairul Taifur had the idea to create a device that could sit within a pond and report detailed telemetry for environmental markers, as well as correct minor water quality issues via the use of a heater and water pump. His system is based around a MKR WAN 1300, which is responsible for collecting data from each sensor and then sending it to the cloud with its onboard LoRaWAN module. To make the system independent from an external power source, Taifur included a small 5V solar panel, power management board, and rechargeable battery pack. Once his firmware had been finalized, everything was carefully placed inside of a waterproof electrical box and sealed to only expose the sensors. This biofloc monitoring system has great potential as a proof-of-concept of how future fish farms might operate in a more sustainable manner. You can read more about the project here on element14.
