Firmware archive named EM_IW522, version 3.0, size 5.88 MB. The name does not identify the brand, device type or board revision, so open it and inspect the files before use; a separate V2.0 package exists as well. Firmware of this kind is usually written to a flash chip with a programmer or vendor tool to restore a device after corruption. Back up the original chip contents, confirm the hardware matches, and check that the image size fits the target flash before writing anything.
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 @biosarchive. Enginerys does not host this file.
