Boardview for the MSI MS-7A78 motherboard, with variant code MS-7A781 in the name, stored as a 6.44 MB CAD file. MSI numbers its boards with an MS-xxxx code, and the trailing digit normally marks a specific version. The file opens in boardview software like OpenBoardView or FlexBV, showing parts and net connections on both sides. Use it to locate components and test points or follow a shorted rail. Check the PCB marking and revision before relying on it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardviews. Enginerys does not host this file.
