Getting started

Requirement:

．1 x Micro-USB cable with data transfer functionality
．1 x Tinker Board power supply* or other qualified 5V/2-3A power supply**
．1 x Monitor
．1 x HDMI cable
．1 x Keyboard and mouse set

* Tinker Board power supply sold separately
** Cable must deliver up to 3A of power output

1. Connect Tinker Board S to a PC using a Micro-USB cable. Within seconds, the PC should recognize it as a USB mass storage device.
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.

Hardware

The Tinker Board S requires 5V/2~3A power via the micro-USB port. The exact amount of current (mA) the Tinker Board S 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 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 Tinker Board S 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 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.

Supported Devices

In general, every device supported by Linux can be used with the Tinker Board S (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 S to reset.

back

One powerful feature of the Tinker Board S 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 S 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 S is equipped with one SPI bus that offers two chip selects. The SPI bus is available on the onboard 40-pin header.
