Boardview for board NS-D012, delivered as a 23.3 KB BRD file with no model information in the name. The small size suggests a daughterboard rather than a main logic board, and NS- numbering is typical of LCFC sub-boards. Load it in a viewer such as OpenBoardView to find parts, connector pins and test points and to check continuity between nets. Before relying on it, match the silkscreen code on your board to NS-D012 exactly, since neighbouring codes belong to different boards.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardviews_schematics. Enginerys does not host this file.
How to open a .brd file
The most common boardview extension. Several unrelated formats share it, which is why one viewer opens a .brd and another refuses it.
