OneBoard PRO+ is an Android Mechanical Keyboard Powered by Rockchip RK3288 SoC

When Coolship keyboard computer was announced in 2013, it caught the attention of some people, but unfortunately the crowdfunding campaign was a disaster despite reaching their funding target,  and few people, if any, ever received the device. But if you are a nostalgic and still would like a Commodore C64-like computer in a keyboard, a company call Acooo has designed OneBoard PRO+ based on Rockchip RK3288 processor and with a backlit mechanical keyboard housed in an aluminum case.

Rockchip_RK3288_Keyboard_ComputerOneBoard PRO+ specifications:

  • SoC – Rockchip RK3288 Quad Core Cortex A17 up to 1.8GHz with ARM Mali-T764 GPU supporting OpenGL ES1.1/2.0/3.0, Open VG1.1, OpenCL, DirectX11
  • System Memory – 2GB DDR3
  • Storage – 16 GB eMMC flash + SD card slot up to 32GB
  • Keyboard – 83-keys QWERTY keyboard with backlit keys made of ABS plastic
  • Video Output / Input – HDMI output, DVI input
  • Audio Output / Input – HDMI, 3.5 mm jack for headphone
  • Connectivity – 802.11 b/g/n Wi-Fi and Bluetooth 4.0
  • USB – 1x USB 2.0 host port for Android only, 1x USB 2.0 port to connect a mouse.
  • Misc – Power button
  • Power Supply – 5V/2A
  • Dimensions – 332 x 178 x 40 mm
  • Weight – 2.76 kg

Android_Keyboard_Computer_DescriptionThe Android 4.4 keyboard comes with a power adapter and cable,  a “PC-line connect cable” with DVI connector on one side, and HDMI + USB on the other side, an HDMI cable, and a “DIY accessory tool box”. The keyboard is actually designed be used both as an Android system and a normal keyboard for your PC or Mac, acting as a dual operating system computer. The connection diagram below makes it clearer.

Oneboard_Pro+_Connection_DiagramSo the PC line is for the display and keyboard connection to your computer, and the video is always outputted via HDMI, but a USB mouse can be connected on a USB port and be used by both the computer and keyboard. The top right Yin/Yang key is used to switching between Android 4.4 and the computer input. Chinese speakers may want to have a look at the promo video.

I quite like the idea, and the design looks pretty neat, although I would have personally preferred a 104-key keyboard with a numpad. The price, however, is what may put off most people, as it sells for $289 on Banggood, or $299 on Aliexpress. For reference, OneBoard PRO+ can be found for 1299 to 2099 CNY on Taobao ($207 to $335 US).

Thanks to Onebir for the tip.

    The price is the killer; maybe 1/2 of it is for the mechanical kb I think…

    Trying to get my head around this. It has an HDMI input and and HDMI output. The output is switchable between the RK3288 running android and whatever is on the HDMI input?

    Could be useful for, say, running Kodi/XBMC on the RK3288 and switching over to the HDMI input for an Xbox or PS?

    or for debugging your android-stuff and switching between that and the pc containing your IDE

    this device seems to me as pure non-sense…

    I love the sound of it, but the price just seems $100 to much! Converting into sterling then I might as well by a cheap windows 8 laptop!

    I’ve just checked backlit mechanical keyboards cost a little over $100 on Amazon – http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Delectronics&field-keywords=backlit+cherry+mx+keyboard

    So this certainly partially explains the price.

    So I bought one of these.

    Experiences so far:

    – Android via mouse and keyboard is a mixed bag. Lots of things don’t work super great. Lots of apps in particular games and emulators don’t handle a non-touch screen well.
    – The Android installation shipped on it is very Chinese. An update or two has improved translation for certain things, but it definitely ships with an interface with many apps and messaging without English translations.
    – I was able to run MAME4droid, an Atari ST, an Atari 8 bit and SNES emulator on it. The two Atari emulator don’t work well with hardware keyboard and mouse — the apps fault, of course, but disappointing. The other two worked great.
    – I was also able to install and run Dolphin Android (Gamecube/wii emulator). Unfortunately the machine is simply to slow to run any games (tried 4 game cube games). Even with the hardware GL acceleration the games ran at 7-10 fps but seemed backlogged on CPU as well, don’t really work.
    – It would be nice to boot into Ubuntu or another stock Linux distribution to make the device more useful, but the device ships with Android installed onto its internal eMMC memory and the bootloader seems to not recognize bootable SD card medium.

    And I should mention that the actual hardware is rock solid. Great keyboard, excellent metal enclosure. Well built, looks great.
