ZIP archive of 111 KB for the Wistron board 11324-1, holding what appears to be a GR boardview file judging by the extension in the name. Wistron numbers its boards with five digits and a revision suffix, and this one is also listed for the Acer V5-431. Boardview data shows component placement and net connectivity, helping locate test points, follow power rails and pinpoint a short. Open it with OpenBoardView or FlexBV, and verify the number printed on the PCB before relying on it.
