Zipped firmware image named UC704UC703.BIN, roughly 2.3 MB compressed, with no brand, model or board number stated. The UC703/UC704 tokens may be version or model codes, but the name does not confirm what device it belongs to. Before flashing, extract the binary, search it for platform and board strings, and compare its size with the target flash chip. Always read and save the existing chip with an SPI programmer first so the board can be returned to its original state if the image is wrong.</description>
