Boardview in .brd format for the Lenovo Flex 2-14d, LF145M mainboard, Wistron board number 13287-1. It shows component placement, net names and pin connections on both sides of the PCB. Open it in a viewer such as OpenBoardView, FlexBV or BoardViewer to locate test points, capacitors on a shorted rail, or the parts named in the matching schematic. Confirm that the PCB carries 13287-1 before using the layout, since different revisions move parts around.
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 @cidschematicandboardviewofficial. 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.
