POWR: System power information

Does “Log”-> “POWR”-> “Vcc: Flight board voltage” measure the voltage from the battery to the flight controller via the power module?
And what voltage does “VServo” measure?

Is VServo the voltage going from FC to servo?

Does “Log”-> “POWR”-> “Vcc: Flight board voltage” measure the voltage from the battery to the flight controller via the power module?

This varies depending on setup.

On our ChibiOS boards this simply comes from an analogue-in sensor on the
CPU.

And what voltage does “VServo” measure?

The servo-rail voltage… typically what the servos are seeing.

Feel free to come up with better wording and create a PR :slight_smile:

If not a ChibiOS board, is it the voltage of the flight controller
