Which Raspberry Pi pins are used by voice hat of 4-Mic Linear Array

I am using 4-Mic Linear array with Raspberry Pi 4. I wanted to know which Raspberry Pi pins are by voice hat.
I could not understand it completely from

system diagram provided.


Hi @Sagar_Shelke, You can see the required GPIO and Power lines in the left side section called Rpi Header.

I saw that but pin names were not clear. Do they have any list of the exact RPi pins used?
