Firmware archive named after the W25Q64BV, a Winbond 64 Mbit (8 MB) SPI flash chip, followed by a date-like code 20210730; no device or board is stated. The name likely reflects a programmer read of that chip type, so the source board is unknown. Identify it by other means before flashing it anywhere. Always save a read of your own chip first, confirm the extracted image is 8 MB to match a 64 Mbit part, and verify after writing.
