Archive in RAR format tied to the Apple iPhone SE, with a size of 4.11 MB. The name does not specify the generation or the kind of material inside, so check after extraction whether it covers schematics, boardview data or both. Such files assist with tracing power and signal paths, identifying components around the charging and display circuits, and locating test points when checking for a short to ground. Compare the logic board numbers on the phone with the files, since a mismatched revision can mislead measurements.
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 @schematicslaptop. Enginerys does not host this file.
