Apple A1502 logic board 820-3476 revision A, packaged as a 1.36 MB RAR archive. A1502 is the model number printed on the case bottom, while 820-3476 is the PCB number found on the board itself; both should match your unit. The archive likely contains schematic and possibly boardview data. Use it to trace power rails, check the charging circuit, locate test points and isolate shorted components during board-level diagnosis.
