Xiaomi Mi 6 schematics, packed into a 738 KB zip archive. The name gives the model only, without board number or revision, so check the version information inside the drawings. Repair technicians use phone schematics like this to follow the PMIC and charging circuits, trace USB-C and display lines, and identify the parts on a rail when chasing a short or a no-boot fault. Expect PDF or image pages viewable in any standard reader. Confirm the PCB version against the document before measuring.
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.
