Circuit diagram in PDF for the Apple A2337 logic board, numbered 820-02016, which is the MacBook Air with the M1 chip. The name gives no board revision, so compare it with the 820-02016-xx marking on the PCB. Apple uses the 820- prefix for logic board part numbers. Technicians use these sheets to trace power rails and signals, follow the power-up sequence and work out which component is pulling a rail low when the board shows a short. Any PDF reader opens it, and the search function helps find net names quickly.
