Apple boardview for the MacBook Pro model A1707, logic board 820-00928, with the name also giving the full part number 820-00928-04. The .brd file is used to locate components, inspect net connectivity and find test points while chasing power rail faults, shorted capacitors or charging problems. It opens in common boardview programs such as OpenBoardView or FlexBV. Apple boards carry the 820 number on the PCB, and suffix variants can differ, so confirm your board matches before relying on part positions.
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. 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.
