Buying guide

If you are looking to acquire an Allwinner based device, then chances are that you are looking for the device with the best community support.

While some development boards are very common in our sunxi community, and they therefor are best supported, we have the ability to easily support just about any A10, A13, A10s and A20 based device (support for newer SoCs, like A31, A23 and A31s, is still lagging behind). This means that we can easily bring up previously unknown devices, but it might still be a good idea to choose the best known hardware.

Recommended Development boards

Open Source Hardware

At sunxi we fully support the OSHW initiative, as this gives people the freedom to adapt hardware designs to their own needs.

Olimex

Currently, Olimex is the only company creating Allwinner based OSHW, and Olimex actively contributes to the sunxi project. We particularly recommend:

  • A10-OLinuXino-LIME: An ultra cheap board with 512MiB RAM, HDMI, ethernet and SATA.
  • A13-OLinuXino: A more full featured board with 512MiB RAM, optional 4GB NAND and optional 4GB Wifi.
  • A20-OLinuXino-LIME: Based on the A10-OLinuXino-LIME, but with a more advanced A20 CPU.
  • A20-OLinuXino-LIME2: Similar to A20-OLinuXino-LIME, features 1GB RAM and Gigabit ethernet.
  • A20-OLinuXino-Micro: Powerful and complete Olimex board, with 1GB RAM, 4GB NAND, ethernet (100MBit/s), SATA and HDMI.

Olimex devices offer a lot of expansion possibilities through GPIO connectors, or Olimex's own expansion modules.

Community Hardware

Some companies actively participate with and contribute to the sunxi community. While they don't always produce OSHW devices, schematics tend to be available.

Cubietech

Cubietech has been working with the sunxi community from the start, and the devices they create come with full schematics.

  • Cubieboard: The original cubietech board. Comes with an A10 SoC, 1GB RAM, 4GB NAND, SATA, Ethernet and HDMI.
  • Cubieboard2: An updated cubieboard with an A20 SoC.
  • Cubietruck: A full featured A20 board with 2GB RAM, 4GB NAND, Gigabit ethernet, WiFi, SATA, Bluetooth, HDMI and VGA.

Rhombus Tech

Rhombus Tech has been working on creating a proper free software supported device since the start, they started the initial community that formed around Allwinner SoCs. They are working on a modular platform called EOMA-68, with plans for a modular tablet and netbook. Sadly, hardware is not easy to get by yet, and we hope that this changes soon.

Recommended tablets

This section is still under construction and no particular tablet recommendations are available yet. While we can hardly expect the tablets to be proper OSHW hardware, some tablets are expected to be much less problematic than the others for free software enthusiasts. A preliminary checklist for the wanted features:

  • The device should be preferably easy to identify and the advertised specs should be reasonably accurate (trying to buy an Allwinner tablet and getting a Rockchip, Mediatek, Amlogic or Active instead is not always a pleasant surprise). If you are buying a no-name tablet from Aliexpress, Amazon or Ebay, pay special attention to negative reviews even if the vast majority of reviews are positive. Even if the description clearly states "Allwinner", it may still have a different SoC under the hood. Most users are happy as long as their cheap tablet just boots some sort of Android and works with it. But a few people who actually care about the SoC choice, may leave a lone warning somewhere in the comments.
    • Read reviews of the device. eg. WiFi reception, screen durability and brightness, touch response, build quality and many other features of the tablet cannot be determined from a vendor specification. If the device is not identifiable easily enough that you can find reviews of it or that you can be sure the review actually applies to the device you are ordering you will never know what you get.
  • Availability of the stock firmware for download from the vendor site (for unbricking)
  • Availability of the firmware sources (for GPL compliance)
  • Good support for the peripherals (touchscreen, WIFI, ...) in the mainline kernel and sunxi-3.4
  • Reasonable features (screen resolution, screen quality, HDMI/USB connectors, battery capacity, ...)
  • Reasonable price

Somewhat worldwide available brands that produce Allwinner based tablets include

Please add any other producers of recognizable Allwinner based hardware that you find.

Other devices

If none of the above boards suit your goals, then there are plenty more devices to choose from:

As previously stated, we have the ability to easily support previously unknown hardware, so the above list should not limit your options.
