To provide the flexibility needed for different builds and projects, Tinker Board features 2GB of LPDDR3 dual-channel memory. Tinker Board is also equipped with an SD 3.0 interface that offers significantly faster read and write speeds to expandable microSD cards used for the OS, applications and file storage.

    Robust GPU Performance & Functionality

    Featuring a powerful but energy-efficient design, Tinker Board supports next-generation graphics and GPU computing API's. Powered by an ARM-based Mali™-T764 GPU, Tinker Board's GPU and fixed-function processors allow for a wide range of uses, including high-quality media playback, gaming, computer vision, gesture recognition, image stabilization and processing, as well as computational photography and more. Multimedia enthusiasts will appreciate the fixed-function H.264 and H.265 playback support, including playback of HD and UHD video*.

    *HD & UHD video playback at 30 fps on Tinker Board is currently only 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

    Further improving on key areas found lacking on many SBC boards, Tinker Board is equipped with an HD codec that supports up to 24-bit/192kHz audio. Its integrated audio jack supports audio output and a microphone in, without an extension module.

    Maker-Friendly, with IoT Connectivity

    Tinker Board features standard maker connectivity options, including a 40-pin GPIO interface that allow for interfacing with a range inputs from buttons, switches, sensors, LEDs, and much more. Tinker Board is equipped with one DSI MIPI connection for displays and touchscreens. The secondary CSI MIPI connection is for connection to compatible cameras allowing for computer vision, and much more.

    Tinker Board 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 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 also features a full-size HDMI output. Additionally, it includes four USB 2.0 ports for extensive peripheral and accessory connectivity.

    Enhanced DIY Design

    Careful consideration went into the design and development of the Tinker Board to ensure that it provides a superior user experience for first-time builders or for seasoned hobbyists. Builders will appreciate the color-coded GPIO header, which makes it easy to recognize respective pin headers.

    The PCB dimensions and topology of the Tinker Board 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 color-coded pull tabs.

    Tinker Board also includes a heatsink, which helps improve heat dissipation under heavy loading or in hot ambient environments.

    TinkerOS ‧ Supported OS ‧ Applications

    A Debian-based distribution ensures a smooth and functional experience, directly out of the box. Whether it's browsing the web, watching videos, or writing scripts, TinkerOS is a great starting point for your next project or build.

    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 optimized 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 optimized. 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 also support the Android Operating system. This allows for an entirely different usage scenarios ranging from media playback, gaming, and much more.

    Tinker board is also working closely with a wide range of popular applications to enable support & optimize functionality.

    The tinker board requires 5V/2~2.5A power via the micro-USB port. The exact amount of current (mA) the tinker board requires will depend on what's connected to it. For general use, a 2A power supply from a reputable retailer will provide ample power to run your tinker board.

    Typically, tinker board 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 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 tinker board is equipped with four USB 2.0 ports. These are connected to the GL852G USB Hub from the upstream USB port via the RK3288.

    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 and the USB hardware on desktop computers, laptops and tablets.

    The USB host port inside the tinker board 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.

    Supported Devices

    In general, every device supported by Linux can be used with the tinker board (exceptions are detailed below). Linux offers a comprehensive driver database that supports legacy hardware for most operating systems. TinkerOS and it's Debian kernel have a large number of inbox drivers for common peripherals & devices.

    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

    The device advertises its own power requirements to the USB host when it is first connected. In theory, the actual power consumed by the device should not exceed stated specification.
    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 to reset.


    One powerful feature of the Tinker Board is the row of available GPIO (general purpose input/output) pins along the edge of the board. These pins are a physical interface between the Tinker Board and the outside world. At the simplest level, you can think of them as switches that can be turned on or off. Of the 40 pins, 28 are GPIO pins (shared with SPI/UART/I2C pins). The Tinker Board is equipped with one SPI bus that offers two chip selects. The SPI bus is available on the onboard 40-pin header.
