    Features & Functionality

    Class Leading Performance

    Using a powerful and modern quad-core ARM-based processor, the Rockchip RK3288, tinker board offers significantly improved performance, versus other popular SBC boards. Realizing the growing demands of different builds and projects, the tinker board features up to 2GB of LPDDR3 dual-channel memory. Tinker board is also equipped with an SDIO 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, the tinker board supports next-generation graphics and GPU Compute API's. Powered by an ARM-based Mali T764 GPU, the 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 is currently only possible via the Rockchip video player, which is limited to support under TinkerOS. Currently, third-party video players and applications may not offer hardware acceleration and may likewise offer limited playback performance and/or stability. 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 192kHz/24-bit audio. The audio jack can support both audio output and a microphone in, without an extension module

    Maker-Friendly, with IoT Connectivity

    Tinker board features standard maker and hobbyist connectivity options, including a 40-pin GPIO interface. Additionally, it comes equipped with two HD MIPI connections allowing for HD displays and HD cameras. For those interested in network centric or LAN storage they will appreciate that Tinker board features Gbit LAN, which offers superior throughput when compared to traditional 10/100 Ethernet controllers. Furthermore, tinker board's LAN port offers a non-shared bus design which helps to maximize and stabilize throughput, ensuring outstanding concurrent LAN and other onboard bus performance. Tinker board's network connectivity is aided by the inclusion of an integrated shield Wi-Fi and Bluetooth controller, which ensures a reduction in interference and improved radio performance. Enthusiasts will also appreciate the IPEX antenna header that allows for upgrades to the onboard antenna.
    Rounding out its connection options, tinker board also features a full-size HDMI output for connection to TVs, monitors and other HDMI-enabled displays, as well as 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 provide a superior end user experience for first-time builders or experienced hobbyists. Makers will appreciate the improved visibility and clarity of the color-coded GPIO header that allows for quick and easy recognition of respective pin headers. The tinker board's PCB dimensions and topology also mirror standard SBC boards that allow support for a wide range of chassis and physical accessories.
    The PCB also features silk-screening with connection header and location callouts, for improved connection clarity. Onboard MIPI headers also feature contrasting colored pull tabs. Tinker board also includes a heatsink, which helps improve heat dissipation under heavy loading or in hot ambient environments.

    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.


    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.
