Schematic diagram for the Xiaomi Redmi Note 9S, catalogued under firmware but described by its name as circuit drawings, in a ZIP of about 1.93 MB. It should open in an ordinary PDF reader after extraction. Repair work with it includes following power rails from the PMIC, checking the charging path and USB port, reading connector pinouts and finding the parts responsible for a short. The Note 9S is closely related to the Note 9 Pro, so verify markings on the board before relying on part references.
