Apple schematic for the 13-inch MacBook Pro A2338, logic board 820-02773, with revision A given in the name, packed in a 22.5 MB RAR archive. Apple 820- numbers identify the logic board itself, so check the number silkscreened on the PCB before you rely on the sheets. The drawings are used to trace power rails, follow USB-C and charging circuitry, and locate the parts behind a short. Pair the schematic with a boardview viewer to find physical component locations and test points on the board.
