After launching the Asus Tinker Board 3N single-board computer last summer, Asus is expanding this line of 100mm x 100mm (3.9″ x 3.9″) PCs with Rockchip RK3568 processors.

The new Asus Tinker Board 3N Plus and Asus Tinker Board 3N Lite are the same size and shape as the original, but have key differences in their I/O options.

Asus Tinker Board 3N/3N Plus

The biggest differences I can find are that the Tinker Board 3N Lite sacrifices a few expansion options like an M.2 B Key connector for PCIe 3.0 SSDs or wireless modules, while the Tinker Board 3N Plus is designed for use in more extreme environments thanks to support for significantly colder or hotter operating environments.

The Lite model also has a single Gigabit Ethernet port, while the other models each have two.

List prices range from around $170 to $279 at Amazon, although there are currently 10% off coupons for the higher-priced configurations that make the difference between the Tinker Board 3N and 3N Lite pretty negligible.

As LinuxGizmos noticed, some models are cheaper at Rutronik24, but the Tinker Board 3N Plus is on backorder at that store.

Here’s an overview of key specs for each of the Tinker Board 3N series devices:

  1. I get it, you’re probably getting higher quality and better / longer support from a large established brand like Asus, but for the price (or only very slightly more) I really think they should be able to offer something with a higher performance SOC like the RK3588.

  2. Even at half the price…I’d pass. These arm SBC’s have pricing control issues. WAY too many alternatives to this e-waste to justify the cost. I can set up something 25x more powerful for less than half the cost…doesn’t make sense anymore.

  3. As cool as these are, when compared to the competition they fall short with price. BananaPI comes to mind as particular competition and far less expensive. Not sure popular these boards will really be at the price point.
