Seeed Studio XIAO nRF52840 (nonsense) Accessing Mic PIN


Rather new to all of this. I’ve noticed the Non-Sense variant has the 6 pins used with the MEMS Microphone module exposed.
I see which pin would be the L/R pin as well. What Pin number is that pad? I see Pin 13 is for the battery charging circuit.
I don’t have an issue soldering to access this pin, but lack the know how to safely test and figure out what pin relates to this pad.
