Hopefully, section 6 of this guide should help you wrt to physical dimensions of Edison:
Regarding opening .brd files, please use free viewer tool from Cadence site:

This seems much more complicated than what I originally expected this to be.
I read that document, and on section 6 they describe the edison board, but not the mini break out board, which is the one I am looking for.
About the .brd file, I was looking for a linux aplication, but in the end went ahead with windows and use that Cadence software.
Man, that Cadence software is a nightmare. Just to download it was a pain. Then, 3 different options of installers, then, the exe does not work. There are different versions of the exe, just one works. It also uses VS2005... 10 year old based software!
Finally, I got to open the file. There is a Show Measurement tool that allows me to measure stuff on the drawing, but the interface is... let's say not great. Is there a pdf or an inkscape version of the mechanical drawing?.
For example, where can I get the .dxf file shown in section 2.5 of this document?
Anyway, at least I can get the data out of this.
Allegro is the Cadance board design tool which is used for making it out, so Eagle would not be able to open .brd file.
Regarding getting .dxf file, may be Intel folks can help you out, ideally this file should have been embedded in that pdf, but seems that some-how it has been missed.
Feature list regarding breakout board is available @ http://ark.intel.com/products/84573/Intel-Edison-Breakout-Board-Kit
Edison .dxf file can be downloaded from: http://www.intel.com/support/maker/edison.htm#downloads . Check under 'Hardware and Shields' section and download: Intel® Edison Board - DXF file.
Hope this helps.
