F7SR model archive in RAR format, 3.71 MB, the largest in this group. The size implies a sizeable schematic or several bundled files, but the name gives no board number, revision or document type. Unpack and identify the contents. Use a schematic to follow power rails, enable signals and charging circuitry and to locate test points during fault finding. Boardview files need a dedicated viewer. Confirm the board revision on the PCB matches, and back up any flash chip before writing firmware.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
