Boardview in BVR format, 306 KB, whose short name points to the iPhone SE logic board. No board number or revision is given, so compare the layout with your PCB before working from it. A BVR file shows component placement, part designators and net connections on both sides of the board, letting you click a pin and see every point sharing the same net. It opens in boardview viewers such as FlexBV or OpenBoardView-compatible tools and is useful for locating test points, filter capacitors and shorted lines quickly.
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 @cyberlanelectonik. Enginerys does not host this file.
