Apple iPad Air circuit diagrams packed into a 37.3 MB ZIP, a fairly large set that likely holds several documents. No logic board number or revision appears in the name, so confirm the board version printed on the PCB matches before following the pages. Use it to trace the battery, charging and display power paths, identify connector pinouts, and work out which rail is missing when the tablet will not boot. After extracting, open the contents with a PDF reader or the matching viewer.
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 @esquematicosparatodos. Enginerys does not host this file.
