Another copy of an iPhone 7 Plus boardview marked for the Intel modem version, 13.8 KB in BVR format. The size is much smaller than typical iPhone layouts, so check in your viewer whether it contains the full board or only a fragment. No board number or revision appears in the name. When intact, such a file is used to locate components by designator, trace signals and power rails across the board and choose test points, and it should only be used on phones confirmed to carry the Intel baseband rather than Qualcomm.
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 @GENERAL_SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
