Service schematic for the Xiaomi Mi 12 smartphone, provided in a RAR archive of about 5.05 MB. The name gives no board number or revision. These diagrams let a technician follow PMIC outputs, battery connector and charging circuitry, check display, camera and SIM connector pinouts and identify the components on a shorted line. Extract the archive and view the pages in a PDF reader. Compare main board markings with the document first, as layout details can change between production versions.
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 @mischematic. Enginerys does not host this file.
