Schematic package for the Samsung Galaxy S23 Ultra, model S918B, supplied in a 1.81 MB zip. The name gives no board revision, so check the contents against the markings on your mainboard. Flagship schematics are used to follow the stacked board interconnects, PMIC rails, charging and wireless charging circuits, and connector pinouts while diagnosing boot or power faults. Extract it with any standard archive tool and open the documents in a PDF or image viewer as appropriate.
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 @phoneSchematics. Enginerys does not host this file.
