Boardview for MSI RTX 3080 and RTX 3090 cards on PCB MS-V389 revision R1.1. The .brd file gives component outlines, pin numbers and net connectivity, so a technician can locate a burnt MOSFET, find every capacitor on a shorted rail or identify test pads near the GPU. Tools such as OpenBoardView or FlexBV open it. Use it together with the R1.1 schematic, and check the revision silkscreen on the card, because positions and fitted parts vary across MS-V389 revisions.
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.
