Apple J230 MLB boardview for logic board 820-01958, revision 02. The .pcb file maps every component and net of the main board, so it supports tracing rails from regulator to load, checking which part shorts a line to ground and finding test points for voltage checks. Open it with boardview software such as FlexBV or OpenBoardView. Apple uses the 820-xxxxx numbering for its boards with the suffix giving the revision, so compare the -02 marking on the PCB with this file before trusting pin locations.
