Schematic drawings for the Xiaomi Mi Play, code name lotus, distributed as a 6.22 MB ZIP archive. The sheets show how the battery, charger and PMIC feed the processor and peripherals, with signal names and reference designators a technician needs to measure rails, follow a dead line or locate a shorted capacitor. After unpacking, the pages normally open in a PDF viewer. Check the mainboard revision silkscreened on the PCB against the document, because parts and values can change between production runs.
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.
