Boardview file in .cad format for an MSI board identified as MS-7A38, version 1.0, about 4.64 MB. The MS-7xxx pattern is used by MSI for desktop motherboards. A boardview shows component placement, part references and net connections on both sides of the PCB, letting a technician locate test points, follow a net between parts and find the source of a short quickly. CAD boardview files open in viewers such as FlexBV or similar tools. Confirm that the PCB revision reads 1.0 before relying on the placement data.
