@RandyHarmon thanks for the detail on the proper voltage for the ADC inputs. I didn't realize they were limited to 3.3V on the Pico. On this page the diagram doesn't actually label the ADC ports as 3.3V tolerant like the legend would suggest they should. But I just looked at the standard Espruino board page and that label is indeed there.
Would you be able to offer any guidance on how I can test the mic with a voltmeter to help me better understand its operation? I looked at the specs, but being new to these small electronics I wasn't able to completely understand what voltages to expect coming out of the mic.
Thanks for the quick tips!
Cheers.
