Boardview for the ASUS X507UBR motherboard, revision 2.0, compressed into a 1.09 MB rar. The layout shows component placement, net connections and test points, which helps when following power rails, locating the charging and VRM circuitry or narrowing down a short. Common viewers such as OpenBoardView, FlexBV or ASUS-format compatible tools open it after extraction. Make sure the PCB is marked REV 2.0, since other revisions may place parts differently.
