Can I power Boron from 12v via VUSB/VBUS, charge Lipo, and use USB?

Doesn't directly answer your questions, but maybe these help:

Powering Boron using 12v

Yes. 12v should work on VUSB. I still don’t like how this is never stated explicitly in the docs. You would have to review the Boron schematic on your own and look at how the PMIC (BQ24195L) is connected to the board pins. Then you have to pull the BQ24195 datasheet and look at what that maximum spec is. Here you can see that VUSB labeled on the board is VIN on the schematic: [image] Here you can see that Vin is directly connected to the BQ24195L VBUS pin: [image] Normal operating voltage f…

Powering Boron using 12v

12V on a Xenon or Argon on VUSB will be immediately fatal to the device. Also do not power both VUSB and the micro USB connector at the same time on a Xenon or Argon. 12V on a Boron on VUSB will be OK, as long as you don’t have any other circuitry that is expecting VUSB to be 5V maximum. The reason is that the Boron has a more elaborate power manager IC (PMIC) that is basically the same as the Electron and E Series and can tolerate higher voltages.

I'm disappointed I can't do the same on my xenon.
