The daughterboard pops out of the rear case with relative ease, giving us access to the USB Type-C port and the microphone.

This is a pretty bare-bones part, which means cheap USB port replacements. Historically, USB ports have been a common failure point (although USB Type-C may prove somewhat more robust in that regard).

Unfortunately, USB-C has been having, erm, other issues.

We found a few bits of silicon on the daughterboard:

Qualcomm QFE2550 dynamic antenna matching tuner.

AKM Semiconductor AK8789 Hall-effect sensor

NXP Semiconductor PTN36241G USB 3.0 redriver

ON Semiconductor FUSB340 USB 3.1 SuperSpeed 10 Gbps switch
