Boardview data for board R23-MB-D in BDV format, a different file from the BRD version of the same code and larger at about 900 KB. The name gives no brand or model. BDV files open in viewers such as FlexBV and some versions of Boardviewer, and they show part placement, pin nets and test points used for continuity checks and short hunting. Make sure the board revision letter on the PCB matches D before following component locations.
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 @ITHINKHS. Enginerys does not host this file.
