Merrii_Hummingbird_BoardAlthough Merrii Technology is supposed to be a design house, the PCB design seem to have been outsourced to WITS as the marking at the center bottom part of the PCB implies. It’s also possible the two companies have the same owner(s), and WITS / Merrii products are jointly promoted.

The company provides support for Android 4.2, and Linux 3.4 (sunxi). They can also provide a graphical interface based on Qt for Linux. Hummingbird Android SDK is available publicly, and support and Linux images will be available via the company’s BBS.

Charbax video starts with an introduction of the Hummingbird development system, followed by a visit of the company mostly with hardware, software development, and SW QA departments. At the end of the video, they also show WITS A31 development platform ($1300), as well as several AllWinner core boards.

Hummingbird development system is available now for 299 CNY (~$50) for the board only, and 499 CNY (~$82) with the 7″ touchscreen display (800×600). At least that’s the price shown on Merrii’s Hummingbird page, as the company has also setup an Aliexpress store where these are sold for respectively $80 and $108 sometimes including shipping, sometimes excluding shipping. The board is said to come with a power adapter,a USB cable, and a SATA Cable.

  1. 1000M Ethernet with 100M PHY chip, impressive

    >YPbPr input.
    im sure there are drivers for it …

    >dual-core ARM Cortex-A7 CPU structure, including all the characteristic of Cortex-A15


    >Hummingbird Android SDK is available publicly

    lol sure, if you consider .doc file and SDK
    This is the level of support they provide:

    another shitty 3 students dev house from china with no clue and no documentation 🙁

    btw you can tell they are technically minded people by the way they rar their pdf files to save that 0.05% file size (im not joking). This + the way they lik about spec and provide no documentation or code means they are another fly by night nobodies.

    Lol, I should have clicked on the SDK download link, but I thought it would be another 250 MB or so download with basically the same SDK as others.

    “another shitty 3 students dev house from china with no clue and no documentation”. I can’t agree with the beginning of the sentence, as they must have around 50 people in the company, but the end looks to be pretty correct.

    You can only see 20 something faces on the clip. A lot of them, but still pretty much kids.
    Im sure they support those boards on the domestic market, they looked like designed for educational sector.

    Last time I looked for chip specs I stumbled into Chinese students having ALL the datasheets and source code you could ever want while same manufacturer (Samsung in that case) didnt even bother to fully satisfy GPL, not to mention full documentation.

    Basically it looks like a political/economical move. Enable Chinese to all the knowledge you can get your hands on, but at the same time limit westerners. This way you secure your place as the only source of cheap and quick designs (third rate quality due to lack of collaboration).

    Ill change my mind as soon as Allwinner or Rockchip joins Linaro instead of just taking GPL stuff, heavily modding, and closing it down.

  4. @rasz_pl
    Most probably Chinese students get all the datasheets and source code, although these are probably released under NDA, because there’s very little IP protection in China. Once I had just a Chinese customer ask for the doc and SDK we paid for. Everything is just an FTP server away, or can be found on sites like

    Chinese silicon manufacturers have always been terrible. For cost reasons, we had to switch from Renesas to Holtek MCUs, and the documentation from Holtek was just terrible. This was about 10 years ago, maybe they have improved since then, but I’m not very hopefully. In the case of AllWinner, one reason they don’t have very good documentation is that many of their customers probably take the reference design, do some minor modifications, and use the default Android image. For customers that customize a bit more, and need support in China, they probably just send the FAEs.

  5. i bough merrii a20 board and could not able get any answer from them on hdmi linux setup. they dont even bother replying mails !!!!
