Apple main logic board schematic for project X362, board number 820-00239, provided as a 6.09 MB PDF. Apple uses 820-xxxxx numbers for its logic boards, and the number printed on the PCB must match exactly before you trust any value. Technicians use these drawings to follow power rails like PP3V42 style always-on lines, check enable signals in the power sequence, locate the source of a short and identify component values. Pair it with a boardview of the same number for faster part locating.
