$96 Kingnovel K-R42-1 (MK888) Android Set-top Box Powered by RK3188 Processor

I’ve now got several RK3188 mini PCs, but I hadn’t found full sized set-top boxes based on Rockchip RK3188 quad core processor with Ethernet, and multiple USB ports. Thanks to a post in mini PC G+ community, we have now a nice looking quad core STB called K-R42-1 by Kingnovel, which might be the manufacturer design house behind the device, and sold for  $96 including shipping in one Aliexpress store under the model name MK888.

MK888

K-R42-1 / MK888 Specifications:

  • SoC – Rockchip RK3188 quad Cortex-A9 CPU @ 1.6 GHz + Mali-400 MP4 GPU @ 500 MHz
  • System Memory – 2GB DDR3 SDRAM
  • Storage – 8GB Nand Flash +  MicroSD slot (Up to 32GB)
  • Connectivity
    • 10/100M Ethernet
    • WiFi 802.11 b/g/n with external antenna
    • Bluetooth EDR 2.0
  • Video Output – HDMI 1.3 + AV output jack
  • Audio Output – HDMI + S/PDIF
  • Video Codecs (Decode) – MPEG-1, MPEG-2, MPEG-4, H.263, H.264 (up to 60 Mbps), AVS, VC-1, RV, VP6/VP8, Sorenson Spark, MVC @ 1080p60
  • Video Codecs (Encode) – H.264, VP8, and MVC @ 1080p
  • Audio Codecs – MP1,MP2,MP3,WMA,WAV,OGG,OGA,APE,FLAC,AAC,M4A,3GPP…etc
  • USB – 2x USB Host
  • Misc – IR port
  • Power – 5V/2A
  • Dimensions – 142x95x21 mm

The device is said to come with a power adapter, an HDMI Cable, and a user’s manual. In the picture below from Aliexpress, there’s one additional port referred to as “micro HDMI”, just next to the full HDMI port, but I’m not convinced… It might be a micro USB port instead.

Finally, MK888 is currently running Android 4.1.1, but will be upgrade to Android 4.2.2. At $96, it seems quite cheap compared to RK3188 based mini PCs, many of which cost nearly the same, but with less features.

Nice device with all the usually requested features and others like IR and the price seems decent.
Can’t wait for you to do a review. The picture of the back of the device seems to indicate an external antenna, perhaps the wifi on this thing will be good too.
If so, ladies and germs, we have a potential winner.

It would be interesting to test the data transfer speed via Ethernet port.

It’s a pity it is not gigabit ethernet (as in some i.mx6 based boards which also have SATA)

Anywyas seems to be great product, for me much better than “tv sticks”. I’m wondering why would you need micro-HDMI? Would it be possible to connect 2 displays? Anyways I doubt it can drive double resolution, so another USB port would be more useful.

Probably it’s just micro-USB next to HDMI, not “micro-HDMI”

i hope :
1 that micro-usb(not micro hdmi) and OTG, i need usb-b port (msc).
2 a good Wifi: realtek or ralink have open drivers w/master mode.
3 4.2 upgrade for miracast / miracast.

yes w/av out, xbmc its a winner… but anyone know Kingnovel?, they ‘ve other products?, they support upgrades w/own team?, are open source friendly?… almost like rikomagic?

very interesant, is posible wait for a review here CNX?

also thats weird not only the micro hdmi in picture, also say hdmi 1.3 and follow the g+ link found decode h264 at 60mbps, the last 2 not correspond to rk3188(hdmi 1.4 , [email protected] is reported in a soc comparison review) , so many errors, is not good signal for a unknown kingsnovel, how is the qa+qc w/errors in Pcb?

Way to go with this design! This is exactly what I am looking for – RJ45 connector – SPDIF interface. The question is, can it handle 1080p files and output it in true 1080p @60Hz without a stutter. If that can be confirmed, my order will be placed. Looking forward to the review!

Yes, they claim dual screen is supported. That’s why 2 HDMI ports are present.

Just got it and …
CONS – No 1080p rom , no Bluetooth , and no luck with XBMC 1080p movies even despite the so much more powerful new 28nm generation Rockchip RK3188 which supposed to give away less heat. I don’t see the point of watching 1080p movies on 720p max accepted resolution.

I really like this for use as a music server (i.e. external HDD hooked up to these tiny devices and then these devices hooked up to a small monitor and good speaker system).

I wonder if they would work like this,
AND
– if they can be left on for months together (without getting overheated or melted)
– If they can be controlled from the android phones.

I just got this! And I must say it blows the mk802III out of the water! The external antenna is strong enough to pick up my neighbors WiFi, the mk802III would barely detect mine…and it was in the same room! The ONLY down fall to this, as with every other android on TV thing, is the fact that there’s yet to be one great answer for how to interact with them. The best for normal use is though your phone or tablet but good luck trying to grab and move something around the home screen with that ;-). Over all this thing is blazing fast, little to no lag, streams video perfectly. It is the best that I’ve used.pick one up…just don’t get to antsy because it takes about a month to get it 😉

[…] K-R42-1 (aka CS918 aka MK888 aka …) has been one of the first Rockchip RK3188 Android TV Boxes available on the market, and can be purchased for less than $90 US. Kaiboer F4, discovered at the end of June, has similar specs, but comes with 2 Wi-Fi antennas, potentially improving Wi-Fi reception. The only problem. until now, was that it was not available for sale, but this has now changed, and you can purchase it for $116 including on GeekBuying, renamed as Ugoos UT1. It’s also available on Aliexpress at higher prices at the time of writing. […]

Beyond XBMC ( http://www.freaktab.com/showthread.php?9603-Beyond-XBMC ) has support for RK3188 and 1080p hardware accelerated playback (supposedly – I’m waiting on my $40 CS918 to be delivered, so I cannot test at the moment)

I did find this one one E-bay however,but is was from a pretty new seller,and he never answered my
questions,so I did not buy one.

Seemingly he sold about 55 pieces,so I will be following his feedback profile to see if he really delivered
the goods as advertised.

‘Listing has ended’ 🙁 Maybe a lot from a liquidation or something…
