ASUS Tinker Board 3N (Single-Board Computer/Rockchip RK3568 Quad-Core Cortex-A55/LPDDR4X/Dual LAN/PoE PD/M.2 Expansion) Review
The ASUS Tinker Board 3N is an industrial single-board computer built on the Rockchip RK3568 quad-core Cortex-A55 with LPDDR4X memory, dual built-in LAN ports, PoE power delivery through an expansion module, and M.2 E and M.2 B expansion slots.
Every other SBC in our catalog targets hobbyists, the Tinker Board 3N is built specifically for industrial and embedded deployment, dual built-in LAN ports and PoE support through expansion modules are features aimed at kiosk, signage, and industrial control applications rather than a desk project.
Dual LAN Out of the Box
Most SBCs need a USB-to-Ethernet adapter to get a second network port, the Tinker Board 3N has two built-in, genuinely useful for network appliance or gateway-style projects where a single Ethernet port is a real limitation.
Modular Expansion for Industrial Use
M.2 E and M.2 B slots support 4G, 5G, and WiFi 6 expansion modules along with PoE power delivery, this is a board designed to be deployed in a fixed industrial location and reconfigured for different connectivity needs without a full hardware redesign.
Comparison to Alternatives
Against our own Raspberry Pi 5 8GB, the Pi 5 is the better choice for hobbyist projects and has vastly more community support, the Tinker Board 3N is purpose-built for industrial and embedded deployments the Pi 5 wasn't designed for. Against Radxa's ROCK 5B+, also in our catalog, the ROCK 5B+ offers more raw compute for general SBC projects, the Tinker Board 3N's dual LAN and industrial expansion options are the differentiator for embedded use cases specifically.

Expert Review
Reviewed by Burooj Alam. Rated by us, not by users.
Expert rating7 / 10
An industrial-first board where dual LAN and modular M.2 connectivity matter more than raw compute.
Best for
- Industrial, kiosk, and embedded deployments needing dual LAN and modular connectivity expansion.
Not for
- Hobbyist projects and beginners, the Raspberry Pi 5's ecosystem and community support are a better fit there.
