Compact 507 KB ZIP for the Xiaomi Mi 1S smartphone. The name states only the model, so the contents need checking after unpacking. The small size points to service documents such as a schematic or component layout rather than a full firmware image. Files of this kind help a technician trace supply rails from the PMIC, find connector pinouts and locate test points when diagnosing no-power or charging faults. Confirm that the PCB revision of the handset matches before relying on any component position or value.
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.
