Apple iPad Air 2 schematic in PDF form, about 10.6 MB, with no board number or revision given in the name. The diagrams help a repair tech work through charging, backlight, power-on and data faults by showing how rails and signals connect between the main chips and connectors. Open it in any PDF viewer and search net names to jump between pages. Because tablets can share a model name across cellular and Wi-Fi variants, confirm the board markings on your unit match the document before using measured values as a reference.
