Hi,

I’m looking for ReSpeaker Mic Array v2.0 schematic to understand where the pin header’s pins are from

And is there any pin can be used as GPIO to enable/disable the external device like amplifier ?

Have you thought about changing your mind on this? I would like to know more about this board and see the schematics.

I asked internally, not sure if I could provide schematics. But in actual use, there is no need to care about the internal structure, it is just a USB sound card.
