Small 111 KB ZIP archive named only after the Wistron board number 11324-1 with a GR suffix; the name gives no device model or file contents. The five-digit project number with a dash revision is typical of Wistron, an ODM that built boards for Acer and other brands. Given the size, it may contain a boardview or similar layout data, but that must be verified after extracting. Before using any of its contents, confirm the board number printed on the PCB matches 11324-1.
