Apple logic board schematic for board 820-02009, including the 820-02009-A designation, delivered as a PDF inside a RAR archive. Apple numbers its main boards with the 820 prefix, and the schematic shows power rails, enable signals, SMC lines and component references needed for component-level repair. Use it alongside the matching boardview to trace a missing voltage or a short to ground. The name does not state the Mac model, so confirm the 820 number printed on the board before relying on page references.
