ZIP archive of 5.55 MB intended for the Apple iPhone SE, with no further detail in its name about what is inside. Repair packs of this kind usually hold schematics, boardview files or reference images, so check the contents first. With them you can follow signal paths, look up component designators and identify diode-mode reference points when chasing a no-power or no-charge fault. The original SE and later SE models use different boards, so make sure the logic board you are working on matches the documents in the pack.
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 @esquematicosparatodos. Enginerys does not host this file.
