Boardview file for the MSI B450M Bazooka Plus desktop motherboard, model MS-7B90, board version 1.0. The .cad format opens in boardview viewers such as FlexBV, OpenBoardView or BoardViewer. It shows component outlines, part designators, nets and pin connections on both sides of the PCB. Technicians use it to locate test points, follow VRM and chipset rails, and find which part shares a net with a shorted line. Check that the version printed on the board matches 1.0 before relying on the placement.
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.
