This is the preorders page for EOMA-68-compliant A31 Quad-Core Cortex A7 CPU modules. This product will have full GPL Source Code publicly available, and will be suitable for many purposes including Educational and R&D purposes, a USB-OTG-powered Thin Client, use as a Freedom Box, or as an embedded computer, or in the future to drive products such as Tablets, Laptops, IPTVs and Desktop PCs simply by plugging it in. Some options for hardware that is on the roadmap are described as example motherboards on the EOMA-68 page, and there are a number of community ideas including the KDE tablet aka Flying Squirrel.

More information and progress can be found at the news page.


The Allwinner EOMA-68-compliant module will have the following features:

  • Approximately Credit-card size format (54mm x 85mm x 5mm high)
  • An Allwinner A31 - Quad-Core 1.2ghz ARM Cortex A7
  • 2gb of RAM
  • at least 1gb of NAND Flash (possibly up to 16gb)
  • Operation as a stand-alone computer (USB-OTG powered)
  • 1080p60 Video playback
  • PowerVR SGX544MP2 3D Graphics, OpenGL ES 2.0 compliant.
  • HDMI, Micro-SD, Micro-USB
  • Gigabit Ethernet
  • EOMA-68-compliant interfaces (RGB/TTL, I2C, USB2, SATA-II, 10/100/1000 Eth)
  • RS232 and JTAG headers


Yet to be determined, but the BOM is likely to be around $50.

Software Freedom Information

Regarding Software Freedom: this CPU Card cannot yet be FSF-Endorseable.
The CEDARX VPU needs a free software library, as does the PowerVR GPU.

How to place a preorder committment

Please read the following so that the forms can be processed by software, later. In the section below "How to order", enter a unique reference into the inputbox and press "Edit", then fill in the fields on the page that is created.

Unique Reference

This is for your convenience: it's actually the name of a unique wiki page that you can link to. If a page (reference) already exists, ikiwiki will try to help you out by appending numbers to the end of it. If you prefer not to do that, just use the back button on the browser and try again.

  • Contact Details: Please remember that the contact details are public, so it is adviseable to be aware of possible spam farming. We do however need to be able to contact you! If you prefer, please create a wiki page, link to that, and place contact advice there instead, or an external URL, or even a link to a google search if you know that you can be easily uniquely identified by any human, using specific keywords.
  • Max Unit Cost: Optionally, please fill in the maximum amount per unit that you would be prepared to pay.
  • Max Budget: Optionally, please fill in the total amount that you would be prepared to spend on units. This will help us when speaking to the Factory.
  • Development Stage: Please clearly state whether you would prefer earliest available sample hardware (which will greatly help support the project), beta hardware (likely to be working but will not have all drivers written), or fully-tested hardware.
  • Purpose: It would help greatly to tell people a bit about what the intended purpose is for: this is a Free Software Community project, and this field is your opportunity to find people who may be interested in collaborating. Feel free to review community ideas, put in a page on this wiki, or put in a URL to an external web site.
  • Status: Please leave this as "preorder" for now, then link to ?done when the modules have been received.
