Tronsmart T428 Android 4.2.2 mini PC Powered by Rockchip RK3188

There have been many new HDMI TV dongle based on the latest Rockchip RK3188 lately, and I listed some of them in comments in CloudnetGo CR9’s post. The only issue is that you can’t buy most of them, just pre-order. Now it seems at least one of them, Tronsmart T428 is available now, and costs $99 on Geekbuying. This mini PC comes with 2GB RAM, 8 GB Flash, Wi-Fi and Bluetooth, and for the first time, AFAIK, a mini PC can be used as Miracast display.

Here are Tronsmart T428 specifications:

• SoC –  Rockchip RK3188 quad core Cortex-A9 up to 1.8GHz + quad core Mali-400 MP4 @ 533MHz

• Video Output – 1x HDMI 1.4

This Android 4.2.2 HDMI TV stick comes with an HDMI cable, a USB power adapter, a USB 2.0 to Micro USB cable (for power), and a user’s manual. The user interface features soft power off, Volume +/-, and full screen mode (Status bar hidden) buttons.

You may have noticed 802.11ac (1.8 Gbps) Wi-Fi support with Broadcom AP6330 module. This seems really high-end, and I can’t find any reference to AP6330. So I’ve asked GeekBuying for confirmation. [Update: Some RK3188 mini PC will use AP6210, others AP6330 like T428. AP6330 can support 5Ghz WiFi frequency, but AP6210 just supports 2.4Ghz. There’s about $10 US difference between the two modules. GeekBuying tested the connection with a 5GHz router and it works, however they don’t have 802.11ac router yet, so they decided to remove 802.11ac from the listed specs for now].

GeekBuying has said they tested WiFi display with XiaoMi 2 smartphone, as well as XBMC 13.0 beta, and both are working fine. They posted a video showing the device in action, and it appears to be very smooth. However, they only showed “WiFiDisplay” application, but did not demo it.

I’ve been told I would receive the device, so you can expect a detailed review soon.
