Perfect for Home Router Projects
The dual gigabit ports work flawlessly with OpenWrt. The metal case keeps the board cool even under heavy network load. Highly recommended for DIY networking enthusiasts.

Robust for Industrial Control
We deployed ten of these for a small factory monitoring system. The all-metal enclosure provides excellent protection against dust and minor impacts. No failures after three months of 24/7 operation.

Best board for learning embedded Linux
As a student, this board offered the best specs for my budget. The 32GB eMMC is plenty for installing multiple development environments. Community support is growing fast.

Great value but documentation could be better
Hardware is solid and the eMMC storage makes boot times very fast. I had to dig through forums to find the right device tree overlays for my specific sensors, but once configured, it runs stable.

Solid hardware, Wi-Fi antenna placement is okay
Ethernet throughput is excellent, hitting near line speed on both ports. Wi-Fi signal is decent but not amazing due to the metal case shielding; use Ethernet for best results.

Smooth Ubuntu Experience
Flashed Ubuntu Core easily. The performance of the RK3566 chip is surprisingly good for the price point. GPIO pins are responsive and easy to control with Python scripts.
Q: Can I run Docker containers on this device?
A: Yes, the RK3566 processor and 2GB RAM are sufficient to run lightweight Docker containers. Many users successfully run AdGuard Home, Pi-hole, and MQTT brokers on this board.
Q: Is the source code for the kernel available?
A: Yes, FriendlyElec provides open-source kernel code and BSP (Board Support Package) on their GitHub repository, allowing for deep customization and compilation.
Q: Does this board support PoE (Power over Ethernet)?
A: No, the NanoPi R3S does not have built-in PoE support. It must be powered via the USB Type-C port. However, there are HATs available separately that can add PoE functionality.
Q: Does the metal case interfere with the Wi-Fi signal significantly?
A: The case has designed cutouts and plastic inserts for the antennas to minimize interference. While there is some attenuation compared to an open board, the signal remains usable for standard home distances.
Q: What is the maximum microSD card size supported if I want to expand storage?
A: While the board comes with 32GB eMMC, the microSD slot generally supports cards up to 128GB or 256GB, though we recommend using high-endurance cards for continuous write operations.
