Circuit diagrams for the Xiaomi Redmi Note 2, codename hermes, in a 2.05 MB ZIP archive. Although the catalogue files it as firmware, the name identifies a schematic. It is useful for following supply rails from the power management IC, checking charge and USB lines, and finding parts tied to display, audio or SIM faults on this older model. Extract the files and open them in a PDF viewer, and compare the board revision on the PCB with the drawings before relying on reference numbers.
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.
