Xiaomi Redmi 2A schematic set, stored as a 5.22 MB ZIP archive although the index files it under firmware. No board number, revision or chipset is stated in the name, so the exact contents should be checked after unpacking. Typical use is diagnosing power, charging, audio or display faults by tracing nets through the PMIC and connectors and locating test points for voltage measurements. Diagrams are usually PDF and open in a standard viewer; verify that the printed board markings on your handset match the documentation first.
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.
