ASUS Tinker Board 2S SBC launched for $120 and up

ASUS unveiled the Tinker Board 2 SBC with faster a Rockchip RK3399/OP1 processor together with the ASUS Tinker Board 2S board that adds a 16GB eMMC flash last October without pricing information. The good news is that the 2GB RAM version of Tinker Board 2S is now available on Amazon and Aliexpress for $120 and up. Note you’ll get a 5% discount if you are a follower on Aliexpress for a total of $132.99 including shipping.

Compared to the first Tinker Board, the new boards are also offered with up to 4GB LPDDR4 RAM, an additional video output option with USB-C DisplayPort Alt mode, an upgrade to USB 3.0 ports and WiFi 5, RTC battery support, and a more stable 12V to 19V DC input.

Rockchip OP1 SBC with eMMC flash, MicroSD cardASUS provides the Debian-based Tinker OS for the board,  as well as Android 10 and Android 11 (Beta) images for the board which you’ll find in the download section together with some other documents. More details may also be found on the documentation page, and support is provided through online forums.

Tom’s Hardware got a review sample in July, and the review is rather negative because of the “slow eMMC” (despite the performance being equivalent to a 16GB Class A1 MicroSD card), some Raspberry Pi accessories like the camera would not work with the board, 1080p video playback struggling in the web browser, and at the time of review, the lack of support for ASUS.GPIO Python library for GPIO control, but it seems to be working now.

ASUS Tinker Board 2S ships with a thick Heatsink, Wi-Fi and Bluetooth antennas, a shielding bag, and a Quick Start Guide. So you’d still need to get yourself a 12V to 19V power adapter, and a USB-C cable for flashing firmware to the eMMC flash. You should be able to use a laptop power brick plus potentially a plug adapter kit to make sure the plug fits into the 5.5/2.1mm DC jack. An alternative to ASUS Tinker Board 2S with the same Rockchip OP1 processor and onboard eMMC flash is the Rock Pi 4 Plus SBC with a much lower starting price of $49 plus shipping, but that’s provided you can find it in this configuration.
