Several interfaces are exposed through USB:

It's possible to make the device switch to fastboot during boot
If the device is not registered, you can switch to mass-storage by selecting "no wifi" during the device boot.

Voltage	3.3v

Here are the chips on the top of the PCB. Caevats:

you need a big screen to view properly the markings as it will line-break with smaller screens
The markings might contain errors as they are tiny and some letter/number could be mixed up
I didn't disassemble it enough to see the bottom because the connectors seemed really fragile (they even had glue inside them) so if I do, I fear that I won't be able to put everything back in place. There might be some more chips on the bottom.
