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.

In a world where energy bills are climbing and the environment is on our minds, keeping tabs on how we use energy at home has become a smart move. Every gadget we plug in impacts our wallets and the planet. That's where home energy monitoring comes in – giving us real-time info on how we're using energy, so we can save money and do our bit for the Earth. This post delves into home energy monitoring, spotlighting how to track your energy consumption using the Arduino Cloud and a Tuya-compatible energy meter with Node-RED acting as a middleware. What's the deal with home energy monitoring? Home energy monitoring is all about watching how much energy we're using at home. It's not just about paying the bills; it's about knowing what's eating up energy, so we can be smarter about it. Why does it matter? Well, first off, it helps us be more aware. When we can see which devices are energy hogs (looking at you, always-on TV), we can take action. And with energy costs going up, finding ways to save money is a no-brainer. Plus, with everyone talking about being green these days, knowing where your energy goes is like a badge of honor for doing your part. The ingredients The key component in this setup is an energy meter designed to monitor both real-time and cumulative power consumption, along with metrics such as voltage and current. This meter is installed within your home's electrical distribution board. Tuya-compatible devices have gained widespread popularity due to their affordability, user-friendliness, and seamless management through the SmartLife application.
