Boardview content for the ASUS M3400QA, revision 2.0, exported as a 1.37 MB PDF rather than a native boardview format. It shows the component placement of the motherboard so a technician can find parts, connectors and test points referenced in the schematic. A PDF version lacks the clickable net tracing of OpenBoardView or FlexBV, so searching by reference designator is the main way to navigate. Confirm the board is revision 2.0 before relying on locations, and use it alongside the matching schematic.
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 @cynetitsolution. Enginerys does not host this file.
