Firmware archive named ZRW115 in a 4.24 MB ZIP, with no brand or model stated. The ZRW token may relate to a board project of the same name, and 115 could be a version number, but the name does not confirm either. Open the ZIP and check the image size against the SPI chip before use. Such dumps are written with an external programmer to recover boards that fail to boot. Compare the PCB marking with any matching schematic, and back up the original flash contents first.
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.
