Circuit diagrams for the Xiaomi Redmi Note 7 Pro, codename violet, packed in a 1.40 MB ZIP archive. The listing puts it under firmware, but the name describes a schematic. Technicians rely on such drawings to trace power rails, identify the parts on a charging or backlight circuit, and pin down short circuits with a multimeter or thermal camera. Expect the extracted file to open in a standard PDF reader, and confirm that the board version printed on the mainboard matches before depending on reference designators.
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.
