That would be a question for the designers.  I could not figure it out
from the context.

I can tell you, based on the Arduino board that is used, and my
knowledge of the pinout, that the sensor uses 5V from the board, and a
ground, and the signal from the sensor enters one of the Arduino analog
inputs.  However, the analog inputs can be used for digital data as well
as analog data, so this is inconclusive.

For the XO, the sensor would require 5V power, perhaps from the USB

I can't tell if the sensor output is compatible with the microphone
