Boardview for an Apple A1278 MacBook Pro 13 logic board, project J30, board number 820-3115 revision B. The 612 KB BRD file is supported by OpenBoardView, FlexBV and Boardviewer. Apple uses 820-xxxx numbering with a letter suffix for revisions. Technicians load it to find components, measure test points, trace power rails and pinpoint shorts on the main supplies. A1278 spans many board versions, so read the 820 number on the PCB and confirm it matches before probing.
