MSI MS-V397 revision R6.0 boardview, for the GeForce RTX 3060. With the .brd file loaded in OpenBoardView, FlexBV or similar software you can click a pin to see its net, list all connected parts and find them physically on the card, which speeds up short hunting, diode-mode comparisons and replacing missing components. Board number and revision should be confirmed on the PCB silkscreen first, since several revisions of MS-V397 exist with different layouts.
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_schematics. Enginerys does not host this file.
How to open a .brd file
The most common boardview extension. Several unrelated formats share it, which is why one viewer opens a .brd and another refuses it.
