Does anyone have examples of large (bigger than what free version can do) boards with 4+ layers and high component density? It does not matter what this board does, I need it for evaluation of some software. I don't care is there is associated schematic, although it would be nice.
The board must be in a new (XML) format.
A little bit late but here's an example
I'm still looking for interesting complex boards, but this one is not in the XML format.
Open the board in Eagle V6 or higher. Then save it. It will be automatically converted to the newer XML format.
