R7000 archive, 243 KB RAR, with no brand, revision or board number in its name. Contents cannot be determined without extracting it, so it may hold a schematic, boardview or firmware for an R7000 device. A similarly sized R7000L-64TC archive also exists, which suggests a related variant, so compare the two before choosing. Match the model and PCB revision on your hardware before use. When reflashing, read and save the original chip first and confirm the image fits the flash size.
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 @cyberlanelectonik. Enginerys does not host this file.
