Hi,
I just created an eagle library for the carambola2 board. Note that this footprint hasn't been tested because I don't have a carambola2 board yet.
File is on github and requires Eagle 6.x (I've used 6.4.0).
If you find any mistakes, please notify me or better: Fork the repository and send a pull request.
