PDF schematic for the Apple iPhone X logic board 820-00863 in its Intel modem variant, packaged as a 3.31 MB RAR. The 820- prefix is Apple's logic board numbering, and the Intel and Qualcomm versions share the number but differ in the baseband section. Use the diagrams to follow PMU outputs, find shorted rails, and check signals for audio, charging or Face ID circuits. Identify the modem on your board before relying on baseband or RF pages, as those sections will not match the other variant.
