Apple logic board 820-1441 package containing a boardview file and schematic diagram, including the IO boards as well as the main board. The RAR is about 2.04 MB. Apple uses the 820- prefix for logic board numbers, which is the identifier to match against the PCB. Covering the IO boards helps trace faults on ports and connectors that sit off the main board. Open boardview files in viewers such as FlexBV or OpenBoardView, and use the schematic to check power rails and signal paths.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
