SUMMARY

The Apple Pencil II operates using inductive charging, facilitated by a magnetic attachment to the iPad Pro, eliminating the need for a lightning port. It connects via Bluetooth for communication and features a conductive tip that mimics finger input. The precise location detection is achieved through a sensing grid beneath the iPad's display, a feature not present in the iPhone. This combination of technologies allows for seamless interaction between the Apple Pencil II and the iPad Pro.

I think the magnetic clip attaches the pencil 2 to the iPad. It uses inductive charging since there is no lightning port on the new iPads and the pencil 2.

Communcationwise, it uses bluetooth to connect to the ipad. The tip is conductive like your finger. I’m not sure exactly, how it figures out location but there must be a sensing grid beneath the display of the iPad something the iPhone doesn’t have.
