3.3.7 Changing the Output Power for Auxiliary Sensors (Vector)
You can change the output voltage level that is supplied to external sensors. This is typically needed
if an external analog sensor (e.g. OBS) operates in a specific voltage range and the raw battery
power does not fall within this range. The default output voltage level is RAW (battery or external
adapter).
