Schematic for the Xiaomi MiPad 4 tablet, code name clover, packaged as a 1.77 MB ZIP archive. The name gives the model and code name but no board revision. Circuit diagrams like these let a technician follow the battery and charging circuitry, trace PMIC output rails, read display and USB connector pinouts, and pinpoint components when a tablet is dead or draws excessive current. Extract the archive and open the pages in a PDF viewer, checking that the markings on the tablet mainboard correspond to the drawings before relying on part 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.
How to open a .zip file
