Boardview in BRD format for Apple logic board 820-02536, 262 KB in size. Only the board number appears in the name, without a Mac model, so confirm the 820 number printed on the logic board before use. BRD files open in OpenBoardView, FlexBV and similar viewers, showing every component position, net name and pin. Technicians use it to find test points, measure diode-mode values and locate a shorted part on a power rail, usually alongside the schematic for the same board.
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.
