At the bottom of the top side of the PCB, on the left side of the cable that goes to the small IR/LED board, you can see a 3-pin header with what may be GND, TX and RX, so this could be a decent Rockchip hacking platform, more practical than RK3188 mini PCs.

Geekbuying also posted some benchmark results: Antutu 3.x (15,245), Nemamark 2.4 (59.9 fps) and Vellamo (HTML5: 1544 / Metal: 491), and tested some features and apps such as Miracast, Video webcam, XBMC, Netflix…

  1. Still seems like the K-R42 is the one to beat for price/specs. There have already been some roms released for it and it available with bluetooth for ~$93. Anyone seen a quadcore with gigabit ethernet?

  2. I have a question: When will can put 1 hard disk in this mini computers? Web browser, films, pictures, libre office and bittorrent. i dont need more, actually my computer spend 30 watts, i want that it doesnt spend too energy.

    Linux distribution or android, i dont care. Perhaps in 2014??

    Several Mele STBs can already do this, and some Geniatech set-top box too.
    With Android, you’ll lose Libre Office, and with Linux, you’ll often lose proper hardware video playback.

    Compulab Utilite should also be able to do what you need, as it runs Ubuntu. You can replace the internal SSD with a larger one. Price is a little higher however.

    I suggest to just attach an externally powered USB 2.5″ HD. The UT1 has spare USB ports. Or plug in a high performance 64GB USB flash drive. I got mine from Dealsprime on express, best price around and I got mine after only a few days. A highly recommended purchase. Thank you Ugoos for a great device!
