Ultimate performance for IoT devices

Enhanced CPU performance

Powered by Arm® 6-core system on a chip (SoC), with the new 64-bit Armv8 architecture — the Rockchip RK3399 — Tinker Board 2S offers significantly improved performance versus compared to other popular SBC boards. It also features Arm big.LITTLE technology, which is a heterogeneous processing architecture that pairs two very different processors together in a single SoC. The big.LITTLE software automates task allocation, ensuring the right CPU core for each process. The upshot is that Tinker Board 2S delivers up to nearly twice the performance of the original Tinker Board, and is significantly faster than many competing SBCs.

Enhanced GPU performance

The GPU bundled with Tinker board 2S is Mali-T860, a multi - core GPU that is the highest performance model built on Arm's Midgard architecture. Specifically, Mali-T860 is designed for complex graphics use cases, and offers full support for OpenGL ES 3.0/3.1, OpenVG 1.1, OpenCL and other frameworks for next-generation and legacy 2D/3D graphics applications. Compared to the original Tinker Board, Tinker Board 2S' Mali-T860 GPU accelerates graphics performance by up to 28%.

Dual-display support

Dual-display support

Tinker Board 2S supports dual displays at up to 4K UHD resolution, so it's equipped for compelling visual output. It also has three popular display interfaces built in, including HDMI, DisplayPort over USB-C and DSI, for superb flexibility.

Wi-Fi and Bluetooth

Next-level 802.11ac Wi-Fi with 2x2 dual-band 2.4/5 GHz antennas deliver transfer speeds that are up to 10X faster than previous Wi-Fi standards. Tinker Board 2S also has the latest Bluetooth 5.0 technology built in, so you'll enjoy speeds that are up to 2X transmit speeds and with up to 4X-greater range. Integrated Bluetooth also opens up the convenience and freedom of wireless connectivity with a wide range of devices, including speakers, headphones and game controllers.
