Solid choice for robotics controllers
Using this as the brain for a mobile robot. The processing power handles SLAM algorithms well. Only minor issue was getting the camera drivers initialized correctly, but support helped resolve it quickly.

Excellent alternative to Raspberry Pi for industrial use
The ROCK 3B offers significantly better performance than standard Pi models thanks to the RK3568 chip. The NPU is a great bonus for running lightweight AI models locally. Setup was straightforward with the official Debian image.

Great hardware, documentation needs expansion
Hardware quality is top-notch and the build feels very solid. While the community is growing, some specific peripheral configurations required digging into forum threads rather than finding clear docs immediately. Still highly recommended.

Reliable and powerful
Been running this 24/7 as a home server for three months without a single crash. The power efficiency is notable compared to x86 alternatives. Very happy with this purchase for my smart home hub.

Smooth Android and Linux experience
Tested both Ubuntu and Android images. Both run smoothly. The video decoding capabilities are impressive for media center projects. The GPIO header compatibility made migrating my old sensors easy.

Perfect for edge computing projects
I needed something with more punch than a Pi 4 for an edge gateway, and this fits the bill perfectly. The dual Gigabit Ethernet option on carrier boards makes it ideal for networking applications. Runs cool under load.
Q: Does the NPU work with TensorFlow Lite?
A: Yes, the RKNN Toolkit allows you to convert TensorFlow Lite, PyTorch, and other model formats to run efficiently on the onboard 0.8 TOPS NPU.
Q: Can I use Raspberry Pi 4 cases with this board?
A: While the GPIO pinout is compatible, the physical dimensions and port placement of the ROCK 3B differ slightly from the Raspberry Pi 4. Most Pi 4 cases will not fit without modification; we recommend cases specifically designed for ROCK 3B.
Q: What operating systems are officially supported?
A: Officially supported OS images include Debian, Ubuntu, Android, and Buildroot. Community ports for other Linux distributions are also available on our forum.
Q: Is the eMMC storage soldered or modular?
A: The eMMC storage is available as a modular component. You can purchase the board without eMMC and add a compatible eMMC module later, or buy it pre-installed depending on the SKU you select.
Q: Does this board support PoE (Power over Ethernet)?
A: The base ROCK 3B board does not have built-in PoE, but Radxa offers a separate PoE HAT accessory that can be stacked on top to enable this functionality.
