Boardview for revision R2.1 of the MSI MS-V389 board, which serves both RTX 3080 and RTX 3090 cards. The .brd file maps every component and net so you can find a part named in the schematic, see its neighbours and track a signal or rail across the PCB, useful for checking resistance to ground and finding test points. Load it in OpenBoardView or FlexBV. Board revisions of MS-V389 differ in layout details, so match the R2.1 marking on the PCB before you start measuring.
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.
