The circuit board layout in the document also matches my particular boardset revision which is a different revision than the one that the original poster has. You’ll notice invvader some lpm the writing on the schematics is barely legible. Feel free to take it and do anything you like with it. Dropbox, SkyDrive, or Google Drive share.
