Apple A1398 documentation for logic board 820-00138, with schematic drawing number 051-00330, packed in a 1.91 MB RAR. Apple uses 820- for the PCB part number and 051- for the schematic document, so this archive likely holds the matching circuit diagrams. No revision letter is stated, so confirm the board marking. Technicians use it to trace rails, investigate charging and no-power faults, and locate components on the main board.
