About this component
Schematic U1400, labelled as a Wi-Fi/BT module. It gives the phone single-stream 2.4 GHz Wi-Fi and Bluetooth, and can be disabled with one of the hardware kill switches. Board 1.1 changed the circuit around it to fix a Wi-Fi module problem found on 1.0, so parts from very early boards are not interchangeable without checking.
What it does on this board
Combined Wi-Fi and Bluetooth radio.
