Features & Functionality
Robust GPU Performance & Functionality
Tinker Board S has HDMI CEC hardware circuit implemented, with the supported software, it allowing multimedia enthusiasts to control TV outputs using a single remote control for a better entertainment experience. Other fixed functions include H.264 and H.265 playback support, as well as HD and UHD video playback.*
*HD and UHD video playback at 30 fps on Tinker Board S is currently available via the included media player. Third-party video players and applications may not offer hardware acceleration, which will result in limited or unstable playback performance. Please refer to the FAQs for more information.
HD Audio Quality
Maker-Friendly, with IoT Connectivity
Tinker Board S also features Gbit LAN for Internet and network connectivity. A dedicated bus resource designed for the LAN port ensures consistent Ethernet performance. The integrated Wi-Fi and Bluetooth controller on the Tinker Board S is shielded with a metal cover to ensure minimal interference and improved radio performance. An integrated IPEX antenna header allows for easy antenna replacement or upgrades.
Tinker Board S also features a full-size HDMI output. Additionally, it includes four USB 2.0 ports for extensive peripheral and accessory connectivity.
Enhanced DIY Design
The PCB dimensions and topology of the Tinker Board S align with standard SBC boards, allowing support for a wide range of chassis and physical accessories. The PCB features silk-screening with a connection header and location callouts, for improved connection clarity. The onboard MIPI headers also feature colour-coded pull tabs.
Tinker Board S also includes a heatsink, which helps improve heat dissipation under heavy loading or in hot ambient environments.
TinkerOS ‧ Supported OS ‧ Applications
Furthermore TinkerOS has been carefully designed to be extremely lightweight and responsive. Running on top of the base Debian 9 is a the LXDE desktop environment. This GUI is optimised specifically for SBC boards. It also features plug & play NTFS support allowing for easy access to Windows based flash drives and external hard drives. The included web browser has also been carefully selected and optimised. It based on Chromium allowing for speed and stability along with a number of extensions. The ASUS team has help to enable hardware acceleration of the browser allowing for improved web rendering and video playback including HD resolutions in YouTube.
TinkerOS also includes a number of popular applications allowing for easy programming and development. These include IDLE / Python as well as Squeak / Scratch.
Beyond TinkerOS and its Debian Linux offering Tinker Board S also support the Android Operating system. This allows for an entirely different usage scenarios ranging from media playback, gaming, and much more.

2. Download the TinkerOS image from the website and flash it into Tinker Board S using third-party ISO software such as Win32Disk Imager or Etcher.
3. Connect the power supply, keyboard, mouse and monitor to your Tinker Board S to boot up.
Typically, Tinker Board S uses between 700 to 1000mA, depending on which peripherals are connected. It may use as little as 500mA when no peripherals are attached. Maximum power for the Tinker Board S is 1A. If you need to connect a USB device to bring power requirements above 0.5A, then you must connect to it via an externally powered USB hub.
The USB ports enable the attachment of peripherals such as keyboards, mice and webcams. This provides the board with additional functionality.
There are some differences between the USB hardware on the Tinker Board S and the USB hardware on desktop computers, laptops and tablets.
The USB host port inside the Tinker Board S is for power supply only, RK3288, was originally intended to be used in the mobile market, e.g. the single USB port on a phone for connection to a PC, or to a single device. In essence, the OTG hardware is simpler than the equivalent hardware on a PC.
OTG typically supports communication to all types of USB devices, but to provide an adequate level of functionality for most of the USB devices that one might plug into a tinker board, the system software has to do more work.
If you have a device and wish to use it with a tinker board, then plug it in. Chances are that it will be compatible. If you're running a graphical interface (such as an LXDE desktop environment in the OS), then it's likely that an icon or other message will pop up to announce the new device.
Port Power Limits
It should be noted that hot-swapping high-powered devices into the tinker board's USB ports may result in a brownout, which may cause the Tinker Board S to reset.
