Rockchip RK3568-powered ASUS Tinker Board 3N is now available in three variants

The ASUS Tinker board 3 was first unveiled in April 2023 before being renamed as Tinker Board 3N later that year, and the three variants of the Rockchip RK3568 single board computer (SBC) are now available.

The standard configuration is the Tinker Board 3N in the commercial temperature range, while the Tinker Board 3N Plus has the same features, except it can operate in the industrial temperature range (-40°C to 85°C). The Tinker Board 3N Lite is a cost-down version in the same form factor, but with a single gigabit Ethernet port without PoE support, no M.2 B-key socket for an NVMe SSD or 4G/5G cellular connectivity, no 16MB SPI flash, fewer serial interfaces, and no CAN Bus.

All three boards can be purchased on Amazon starting at $169.99 for the Lite variant with 4GB RAM and 64GB eMMC flash, and $179.10 and $251.10 for the Standard and Plus models respectively after ticking for a 10% discount coupon. ASUS has an extensive distribution network, so it may pay to shop around, and for instance, Rutronik24’s pricing may be more attractive to European customers, although it’s still fairly pricey for a Rockchip RK3568 board considering you can have similarly featured alternatives such as Radxa Rock 3B or Hardkernel ODROID-M1 at significantly lower price.
