Schematic for the Apple iPhone SE 2020, the second-generation SE, in a 1.16 MB ZIP archive. The name gives no board number or revision. Logic board schematics let a technician follow power rails from the PMIC, check the charging and boot circuits, and work out which components and lines are involved in no-power, no-image or no-charge faults. The file is likely a PDF and opens in any reader, best used together with a boardview to find the parts physically.
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 @schematic_mobile5. Enginerys does not host this file.
