Apple iPad Mini logic board layout supplied as a .bvr boardview, about 165 KB in size. No generation, board number or revision appears in the name, and several iPad Mini models exist, so confirm the match against the markings on the PCB first. In a compatible viewer you can click any part to highlight its net, follow a rail from the battery connector to the power controller and find where to probe with a multimeter. It works well alongside a schematic when hunting a short to ground or a missing voltage.
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 @SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
