Hummingbird A31 Is a $70 Feature-packed Development Board Powered by AllWinner A31

Merrii Technologies introduced the Hummingbird development kit powered by AllWinner A20 last year. Since then they’ve sold 10,000 pieces, and have been working on another development board based on AllWinner A31 with lots of different ports and options, including an optional 7″ capacitive touch screen.

Quad_Core_Hummingbird_development_board“Quad Core” Hummingbird specifications:

  • Storage – 8GB Flash + micro SD card slot
  • Video Output – HDMI, VGA, LVDS
  • Video Input – 3.5mm jack for CVBS (or YPbPr?) In (TV IN)
  • Audio I/O – HDMI, 3.5mm jack for stereo audio, 3.5mm jack for Line IN (Same as TV IN). 2x 15w amplifier on-board.
  • Camera – MIPI interface
  • Connectivity – Gigabit Ethernet, 802.11 b/g/n Wi-Fi and Bluetooth (AP6210 module)
  • Cellular Connectivity – SIM card slot + mini PCIe connector for 3G modem
  • USB – 2x USB host port, 1x micro USB OTG, and 3 internal USB headers.
  • Debugging – UART console
  • Expansion Headers – Two 2×30 headers with access to GPIOs, LVDS, and other signals
  • Misc – Speaker headers, RS485 port, IR receiver, power, reset and uboot keys, RTC + battery slot
  • Power – 12V

 

A31_Hummingbird

Detailed information is not available for this board, but thanks to Charbax video below we know the board will be compatible with the same 7″ display (800×600) support by Hummingbird A20, and the company can provide Android 4.4 and Linux 3.3 + Qt SDKs with full source code for the board. Compared to the previous versions, Hummingbird A31 adds supports for 3G Modules, a VGA interface, and more accessible pins.

The board is available for purchase now via Aliexpress for $70 plus shipping by courier ($15 to $20).

    I thought “no ethernet connector on the picture?”, but I just learned GMAC = Gigabit Media Access Controller, so that must be the GigE

    wish it had a wifi module onboard

    It does. Look to down left corner. AP6210

    @xxiao The A20 Hummingbird has wifi/BT combo. The module in the lower left of the A31 board looks identical to the one on the A20 board, but the photo isn’t clear enough to know for sure.

    @xxiao In the video you can see that it is an AP6210. That is SDIO 2.4Ghz / BT 4.0 combo modules. Same module that is on the Cubietruck. There is chip antenna on edge of board labeled ANT1.

    is this wifi module same as the one on cs868 because that was the only good thing on that device.

  7. May 10th, 2014 at 10:50 | #7

    @Sander
    Yes, some products are specs like that. GMAC = Gigabit Ethernet, EMAC = 10/100Mbps Ethernet.

    @adem
    CS868 has a Wi-Fi module based on Realtek RTL8188EUS with a chip antenna. (No cable inside).

    Hummingbird, Hummingboard – no wonder I was confused!
    http://www.cnx-software.com/2014/04/21/

    So this one has a socket for a sim card because 3G modem modules (as opposed to cased devices) don’t?

    Does this board have a serial ttl connector? What about a fex mode button

    What other IOs it has in these two long headers on its back?

  10. May 17th, 2014 at 11:06 | #10

    @ran
    Yes and yes. It’s in the post.
    For the other, they don’t even have a product page for the board… You could try to chat on Aliexpress to get that information.

    @ran
    Ok, I missed the small uart connector at the bottom of the picture. Perhaps the uboot key is the fex?

    I still wonder if anyone knows what gpios those 2×30 headers offer. Must be most of what the a31 can offer..

    Where do i place an order for the Hummingbird A31 Development Board?

    Is there an fel button on the board?

    very impressive, was waiting for you to come-up with this board, finally is you put all the options on it, thank you

    How do you load OS onto this board?

    Is it VGA out?

  15. July 4th, 2014 at 22:23 | #15

    @Graham
    It should boot from flash or micro SD card. The company should have the images and source code for their board.
    Yes, there’s a VGA port, so it should be able to output to VGA.

    Is this board community supported ? where are the wiki’s, userguides any forums for interacting with other developers ?

  17. July 6th, 2014 at 22:18 | #17

    @vijay
    There’s very little community support for AllWinner A31 is general. The company making the hummingbird should provide you with the documentation and source code, but it’s not available publicly AFAIK.

  18. July 15th, 2014 at 21:45 | #18

    I’m thinking if change from rockchip to allwinner. I planed to buy some development boards for a team project and I thought maybe the Radxa is a very good option for my guys to learn. After find this A31 I though it’s really wanderful, but I don’t see any support or documentation. I probably will need MIPI display output and this one (from their aliexpress shop) looks like have it, the Radxa does not have. I’ll try to contact them tomorrow, if they have documentation maybe I try to work in AllWinner products.

  19. July 16th, 2014 at 18:32 | #19

    We have contacted Merrii today… and the contact girl does not look like she knows anything about development. Also said their tech people mainly does not speak english. Anyway we will try to contact some tech guy there and ask about documentation. I guess they don’t have anything…

    The board looks really good, but even Radxa community looks 1000 times better.

    @Javi
    Radxa and Rockchip support don’t seem to be working towards submitting their code to mainline Linux. Their Linux support is for 3.0 which is a couple of years old. It is easy to hack old kernels, just look up the published exploits that have been fixed in later kernels. Sony lost millions when their Play Station network got hacked because of old kernels.

    The sunxi group is working towards mainline submission of the Allwinner code. A lot of it is already in mainline. Hopefully Allwinner will start participating in this process more directly since they have joined Linaro.

    So for playing around a 3.0 kernel is fine. Just don’t ship any Internet connected products using it.

    @Jon Smirl

    That’s wrong. Rockchip even contributes directly to the kernel.

    I have a project in my hands related to a basic board (quad core) with a small high quality display. It must run Android.

    I don’t have a great knowledge about LCD yet, so the MERRII board has more LCD potential. I found most of 3 to 5 inch LCDs are MIPI. If I understood well, the MERRII Hummingbird has MIPI, as well as LVCD, RGB and HDMI. In detail:

    Dual-Channel LVDS 1920×1080@60fps

    4 lanes MIPI DSI 1920×1200@60fps

    Dual-channel RGB/CPU LCD 2048×1536@60fps

    Integrated HDMI1.4 1080p@60fps

    The Radxa has HDMI, A/V and RGB (in same LCD line than A/V). There is not MIPI there or LVDS, so it’s a problem for me now.

    But also that’s true, Radxa people has some instructions about LCD manage, MERRII does not have anything!

    It will be good if a development board based in a CHINESE SoC is well documented as the SoC manufacturer is even more closed than them.

  23. July 17th, 2014 at 00:43 | #23

    I will need around 4″ LCD ~ 720p (or near). Any way to learn about LCD control managed by Android?

  24. July 17th, 2014 at 15:49 | #24

    Today I could speak in english with a sales. They said will provide documentation in english after buying. They asked why don’t go to visit their office here in Shenzhen… maybe I can go.
