Logic board schematic for the iPhone 11 Pro Max, board number 820-01682 in Apple numbering, bundled with a baseband schematic in one RAR archive of about 1.3 MB. The 820 prefix is used by Apple for main logic boards. Technicians use these pages to trace power rails from the PMU, follow charging and display lines and diagnose baseband or no-service faults. Make sure the 820 number on your board matches before relying on part references, as sister models use different boards.
