Small RAR archive, under 1 MB, for the Meizu MX5 smartphone; the name gives only the model, so the contents are not described. Files of this size in a phone repair collection are often schematic pages or component layout diagrams. A technician uses them to find the correct test points for battery, charging and boot-related voltages and to identify which components sit on a failing line. Open the archive to confirm what is inside and make sure it matches the board revision of the phone being repaired.
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.
