HDMI-stick mini-PC runs Android on quad-core ARM SoC

Aug 21, 2013 — by Eric Brown 41,076 views

[Updated Aug 22] — China-based Ugoos announced a quad-core, HDMI-stick style mini-PC available for a special price of $65 (normally $100). The Ugoos UM2 runs Android 4.2 on a quad-core Rockchip RK3188 ARM Cortex-A9 SoC, offers an HDMI port, WiFi, and Bluetooth 4.0, and provides dual USB 2.0 host ports for external peripheral connection.

Like Rikomagic’s MK802IV HDMI stick computer, the Ugoos UM2 runs Android Jelly Bean on Rockchip’s latest quad-core, RK3188 system-on-chip. Unlike both the Rikomagic, Tronsmart, and most other HDMI dongle computers, however, the Ugoos UM2 offers two USB host ports rather than one, saving the $7 cost and clutter of an extermal USB hub.

Like its rivals, the 142 x 95 x 21mm (5.60 x 3.74 x 0.83-inch) Ugoos UM2 uses a micro-USB port for power, and consumes less than 10 Watts of power when active. The device is equipped with 2GB of RAM, 8GB of onboard flash, expandable to 32GB, and a microSD slot that could bring total storage to 64GB. An HDMI port is supplied, and wireless features include WiFi, Bluetooth 4.0, and an IR port. The device is said to support PPoE, VPN, hotspot networking and offer full DLNA for media sharing. Its Android 4.2.2 build offers Google Play and XBMC support, among other basic apps.

The RK3188 runs at 1.5GHz or 1.6GHz, depending on two different citations on, and features a 500MHz ARM Mali-400 GPU. The same SoC runs on the Tronsmart T428 Android stick computer, which can be had for as low as $74, compared to a low of $80 for the MK802IV. The officially $100 Ugoos UM2 has them both beat on price, at least temporarily, with a special price of $65 at (Click the image at the right to view the Rockchip RK3188’s block diagram.)

  1. Roed Nielsen says:

    The article reports power consumption of 30W, but a 5V 2A power supply (10W). Obviously, there is a mistake somewhere. I tend to believe the 10W number.

    • LinuxGizmos says:

      Yes, you are definitely correct, since its included power supply is rated at 5V/2A. We edited the article to show “less than 10W power when active.” Sorry about that error and thanks for catching it!

  2. Mike says:

    It would be great if this thing had an ethernet connector!

  3. Maxim says:

    I can see the Russian flag in their logo however they are claimed as a Chinese factory. It’s interesting if they have Russian roots

  4. Skip Ferderber says:

    Your review says this gadget can be expanded to 32gb of on-board memory. Can you buy it with the expanded memory…or how can a “civilian”easily add it onto the device? I understand expanding memory by using an SD card but expanding internal memory is always preferred. You also fall to make mention of access to the Google Play store. Should I assume that’s implied?

    • Paul says:

      SD card should be assumed. Google play is accessable by the andriod OS. This comes with andriod installed.

  5. Paul says:

    “◦Consumption — less than 10W ”

    The manufacturer specs state 30W. I’d be interested to see real-world numbers. I look briefly for a youtube video or something of that nature where somene measured it at idle and under load but found nothing.

    Chinese and Russian tech. This should complete the surveillance network just fine :)

    I joke. I’ll probably get one.
