BRD boardview of around 780 KB titled only NCWG0, which is too short to name a brand, model, board maker or revision, so the hardware must be identified by its PCB markings. BRD files open in programs such as OpenBoardView or FlexBV and show component outlines, pin numbers and nets on both sides of the board. They are used to locate parts, follow a rail from its regulator, find test points and isolate shorted components. Compare the layout with your board carefully before working from it.
