Free ECB_AT91 V1 (Single Board Computer)
The Free ECB_AT91 V1 is a Single Board Computer made by emQbit. You can download the specs and build your own. We really think that it is very important to have a free modern embedded plataform : Hardware and Software.
You can download the designs and use/modify them. They're copylefted under the GNU GPL license. (We might upgrade to GPL V3 once it's ready).
Hardware is Useless with no software, so the documentation and the patches needed to make it work are also available.
Feel free to contribute. If you want to support our work, please donate some money or contribute documentation, debugging, tools, etc. Buying products or support from us is a good way to contribute.

Inspiration
There are similar projects, and we would like to thank them for making their designs free and for their support.
Openembedded
Stefano Parusso motivated us to use openembedded in the board (by making OE run on it!). We are testing it and it's working well. We are using the Angstrom Distribution, which is part of OpenEmbedded.
We will publish the repositories and the base image really soon.
