Xiaomi Mi 8 circuit diagrams, identified by the code name dipper, supplied as a compact 909 KB ZIP archive. No board revision is noted in the name. A schematic for this phone is useful for tracing power rails from the PMIC, following charging and fast-charge paths, checking display, camera and fingerprint connector pinouts, and locating the part behind a short or missing voltage. Open the extracted file in a PDF reader, and match the board markings on the handset against the pages before trusting component designators and values.
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.
