Xiaomi Redmi Note schematic set, packed into a 2.62 MB ZIP archive. The name gives no codename or variant, so it may cover the original Redmi Note and the exact board version should be checked against the sheets inside. Although filed as firmware, it is a service drawing used to locate components, follow power and signal nets and find test points during board-level repair. Open the extracted pages in a PDF or image viewer and compare chip markings on the PCB with the drawing before working from it.
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.
