Apple boardview for the J43 project, logic board 820-3437-B, in BRD format inside a 194 KB RAR. The 820 prefix is Apple's logic-board numbering, and the trailing letter marks the board revision. BRD files open in OpenBoardView, FlexBV and similar viewers, which show part placement, nets and test points, useful for tracing shorts on power rails or locating a damaged component. Check that the board number and revision letter printed on the PCB match before relying on it.
