RAR archive of 2.54-ish size class, 2.64 MB, containing boardview data for the Apple iPad 4 logic board. The name lists no 820- board number, revision or Wi-Fi versus cellular variant, so compare against the number silkscreened on your board first. A boardview lets a technician locate components, connector pins and test points and follow nets across both board sides, which speeds up tracking a shorted rail, a damaged backlight circuit or a failed charging path when working with a multimeter and power supply.
