Generic archive labelled for the Xiaomi Mi Note 8 Pro, in rar format at 1.72 MB, with no further description in the name. Its contents could be a schematic, layout or small service file, so extract it and identify the documents before use. For smartphone board repair, such material helps locate components, follow power rails from the PMIC, and check charging, backlight or USB lines. Confirm the board version printed on the phone's PCB matches whatever the archive contains before relying on component 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 @SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
