At the end of February 2006, the Open Graphics Project team released schematics for their development board, OGD1. An article on KernelTrap [1] was written about this, explaining the release under GPL and the nature of PCB schematics (logical connections between chips) and artwork (physical component placement and circuit trace routing). Just last Friday (2006-05-26), we announced the first draft [2] of the artwork. For the most indepth information, check out the OGD1 page on the OGP Wiki [3], which links to PDFs for each of the routing layers and a way-cool composite image of all of the layers.
