AirTag 2 Die-Shot Teardown Reveals Its Silicon Story
Hackaday walks through a die-shot teardown of the Apple AirTag 2, exposing the device’s silicon stack: a Nordic nRF52840 Bluetooth SoC, a large UWB chip assembly with a visible die for precise localization via an antenna network and time-of-flight, plus a Bosch accelerometer and an SPI memory. The article explains how the UWB system uses multiple antennas for localization and notes that the speaker, tucked deep inside, can be disabled non-destructively, though the process is non-trivial.
