Apple MacBook A1502 schematic bundled with a boardview, board number 820-3476 revision A, packed into a 2.64 MB RAR. Apple numbers its logic boards in the 820-xxxx format, so the number on your board must match. The PDF schematic serves for tracing power rails and signals, while the boardview, opened in tools such as OpenBoardView or FlexBV, locates components and test points on the PCB. Together they help find shorts and missing voltages; check file contents after extraction, as the misspelled name gives no format details.
