ASRock FM2A75M-DGS boardview at revision 1.02, stored in a ZIP of roughly 334 KB. This AMD FM2 micro-ATX board can be examined part by part in a viewer, with nets highlighted to show every connected pad, which speeds up locating shorts, broken traces and the source of each power rail. FlexBV, OpenBoardView and similar tools read such files. Before relying on it, verify that the revision silkscreened on the PCB matches 1.02 so the layout corresponds to your board.
