From the project

Flexible circuit board design for adding a headphone jack to an iPhone 7

The design of this project is free for everyone. You have my full permission to make modification and improvement however you like.

Here is a picture of the board on the bottom flex cable.

I have used the internal circuit board from an official Apple headphone adapter. The circuit connects this board to the lightning jack on the bottom flex connector. When something is plugged into the lightning jack, the signal is switched from the headphone adapter to the lightning jack. There is a 1 megaohm resistor that pulls the shield of the lightning connector to 3v. This is shorted to ground when a…
