Xiaomi Mi Box Mini Unboxing

Xiaomi Mi Box Mini is probably the smallest Android media player available so far. It integrates a 100-240V power supply, and only features a single HDMI output port, no micro SD slot, and no USB ports. Although the device is primarily targeting the Chinese market, with a Chinese user interface and CCC certification only, several Chinese e-retailers have started to offer it for $50 or less.  GearBest sells it for $42.98 with coupon MIBOX, and they’ve sent me a sample for review. Today, I’ll post some pictures of the device, before doing a review, including trying to switch to a user interface in English.

I’ve received the package via DHL, and for once I did not have pay custom duty or other tax.

On the back of the package, they listed some key features in Chinese, such as H.265 1080p video playback, quad core processor, hexa core GPU, 1GB RAM, 4GB flash, dual band Wi-Fi, Bluetooth 4.0, and DTS and Dolby support.

The package includes the media player, a Bluetooth remote control with a CR2032 battery (included), a long HDMI cable (1.5m), and a user’s manual entirely in Chinese. Gearbest also added an adapter for British sockets.

There’s no much to say about the device itself, except it’s tiny and feature a lonely HDMI port. The power pins are retractable.

Xiaomi Mi Box Mini Teardown

At this point, I would normally take out my toolset to try to open the enclosure, and check out the board(s). But Xiaomi made it very difficult to do so, and I did not manage to open it without risking breaking the case. Luckily, somebody has done it already, and the first picture clearly shows how they struggled to open it, breaking part of the case to open it.

Xiaomi_Mi_Box_Mini_NAND_FlashBeside having a hard-to-open case, I can’t see any obvious way to hack the device, for example connecting a UART console, or adding a USB port. The next step is to try options to switch the firmware or at least some apps to English, as the firmware is said to be entirely in Chinese only, before doing a full review.

I’d like to thank GearBest for sending a sample for review. They sell it  for $42.98 with coupon MIBOX, but there are also other options such as GeekBuying, Aliexpress, or eBay.

  1. The MT8685A has support for SD Card, USB and Ethernet. They just aren’t exposed on this unit.

    Has anyone located a datasheet for the MT8685? I want to check out what kind of audio support it has and there is not enough information available to tell.

    Just another chip to add to my pile of ignored products while waiting to see a datasheet.

  2. @Jon Smirl
    The device can connect to my 5GHz router, so it’s definitely dual band.
    There aren’t any info about MT6225N on the net, not sure why Mediatek don’t document all their chips…

  3. @cnxsoft They do document there chips, they just don’t let other people have the documentation. I understand why places like Qualcomm/Marvell do that – if you won’t give those companies a PO for a million chips they don’t want you as a customer. But these Chinese companies are not like that, they want to sell their chips to everyone. So it makes no sense, they are copying Qualcomm (closed doc, few customers) while acting like TI/Freescale (open doc, many customers).

  4. un-fused fire hazard. Period. These cheap 240v to 5v converters kill, and that psu is a cheap catch fire type converter, Can’t see a regulator so probably a cheap zener too, caps don’t look rated to 240v….140v that cap says. Should be 240V~ for EU. It says to me “cheap tat”.

  5. @Gabe I wonder how the cost of this CPU set (CPU+external radio chip) compares to alternative CPU plus Ampak module. Alt+Ampak is about $9. If this chip set is ~$6 it is worth looking at. This Xiaomi mini box makes me think it is around $6.

    Zoobab – the linked article says it is a 5V power supply. It looks like there is PMIC chip on the CPU PCB making the rest of the voltages.

    is it just 11N or 11AC?

  6. @Jon Smirl

    Mediatek is a Taiwanese company, not Chinese…
    Besides, you might see them as a company that makes cheap junk, but they’re in fact chasing the big boys and are very likely to overtake some of them within the next couple of years.

  7. I just receive my ,two days ago,, and after updating to 1.3.87 ( I think ) i found my self in endless boot loop.
    now there no way to hard reset no way to reflash the firmware so what to do?

  8. I bought one from aliexpress and receive it in Brazil few weeks ago. It is really nice both the device and the remote control. The positive aspects for us, outside China, is finished…
    My device at least is in Chinese only. No setup available to change that to English. Only cumbersome methods to install other launchers or install apps via apk.
    After loosing many hours, I managed to connect to wifi, access my laptop and install netflix (via apk). Another
    disillusion. Important functions in the app are not accessible by the remote (like language, account, chapters navigation).
    As it no longer has a USB slot, it is not possible to use a remote mouse to overcome this limitation. Tried to adopt the wifi/bluetooth mouses app I found and did not manage to be succesful (wip, android remote, remote tablet,…).
    In addition to this issue, netflix streaming presented many tiny bugs during the tests I did. It is not a pause to receive data, it impacts the image refresh, which including gives airsickness.
    If anyone found out any way to overcome that, I would be highly grateful. The intention was to give it to my elderly father, who does not manage to use devices other than remote control to watch TV.
