Daring Fireball‘s John Gruber said Monday that he has confirmed “with a little birdie” that there is indeed no U1 chip in the new iPad Pro.
The U1 Ultra Wideband chip debuted with the iPhone 11. It allows the iPhone to detect its exact position relative to other devices in the same room. That gives it a sense of spatial awareness for things like targeted AirDrop by pointing one iPhone at another to share a file.
