Schematic diagram for the iPhone 6S, code N71, logic board 820-5507-A, in a 4.28 MB RAR. The -A suffix marks the board revision, following Apple's 820-series logic board numbering. Technicians use these pages to follow the PMU and charging rails, check NAND and baseband power, and find shorted components on this double-sided board. Open the extracted document in a PDF reader, ideally with a matching boardview. Make sure the number on the logic board matches 820-5507, because 6S boards vary by baseband supplier.
