Raspberry Pi 3 B+ & 4 mic array

hi @bill.yu



My questions are in my original post.

However, when I take it off board (not just pushed into all of the pins as I am going to need many of the pins for sensors and IR and RF.



I’ve used the pinout diagram on page 3 of the attached official doc. It’s not working. Is this incorrect? If so, what are the essential pinouts to make it function. It would seem that it certainly doesn’t need all of the GND or 5VO.

I’m especially interested in the GND and power as I’d like to use them to add additional things to the Pi.



Thanks.
