CX-921 TV box mini PC features RK3188 quad-core CPU for $69

cx921The team behind the CX-919 TV stick mini PC looks like they’ve pressed to Go button a new TV box style model with very similar hardware called the CX-921.

The new model features Rockchip’s popular RK3188 quad-core SoC CPU inside an AppleTV-like chassis measuring 98 x 98mm square and 22.3mm thick.

There are two versions, basically just whether you get 1GB or 2GB of DDR3 RAM. However, the internal storage is fixed at 8GB – you can expand that either with MicroSD card, up to 32GB; or through the two USB2.0 ports on board with external hard drives. The CX-921 comes with HDMI v1.4 video output and composite AV output, along with standard 802.11b/g/n Wi-Fi and RJ45 Ethernet connection.

It’s preloaded with Android 4.1.1 (Jelly Bean) but there’s no word on whether it will be upgradable to Android 4.2.2 and if so, when.

It’s hard to know who actually makes these things as there are so many different sellers around but it’s possible the CX-series could be made by Shenzhen SXV Technology.

The RK3188 is a quad-core SoC CPU based on ARM’s Cortex A9 design but manufactured at a more power-efficient 28-nanometre scale. It’s graphics performance comes courtesy of ARM’s own Mali-400 MP4 quad-core graphics engine.

Given the quad-core performance on this one, it’s somewhat surprising that according to Androidpc.es, it’s available at an already low $US69 on Aliexpress excluding shipping. But that’s the nature of the market at the moment – you can’t sit still if you’re making mini PCs.

    Unless I missed something essential, then the Kingnovel K-R42-1 appears to be the better option, since it is available for $87 incl. S/H, but additionally offers:
    2GB of RAM, optical S/PDIF output, an IR remote control, also RTL8188 WiFi plus external antenna and a stronger 2A SMPS.
    Additionally by the end of next months an upgraded version with Bluetooth is expected.

      I think I’d like something with more than two USB ports. Once you get a mouse and keyboard in, you need a hub for other devices.
      Cheers,
      Darren.

    That’s why I like to have built-in Bluetooth, to keep the USB ports free for more ‘important’ devices ;-)
    But I agree, 4 USB ports would be more desirable. Maybe the upcoming 4-core Amlogic AML8726-M8 will produce some more interesting designs in a few weeks – or maybe just only the same once again.

      Built-in is good, until it stops working. At least more USB ports gives you options. Yeah, it’ll be interesting to see what new designs we see.
      Cheers,
      Darren.
