Boardview for the ASUS GL552VW motherboard, revision R2.0, board number 60NB09I0-MB3100. It pairs naturally with the R2.0 schematic: the schematic explains the circuit while this .brd shows where each part and test point physically sits on the PCB. Open it in OpenBoardView or FlexBV to search reference designators, highlight nets and locate shorted components. ASUS uses the 60NB prefix for its own board numbers, so read the full code on your board and confirm it matches before relying on the layout.
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.
