M5Stack Fire Microphone?
Does the M5Stack Fire have a microphone?
The advertising says it does.
There are internet references to a MEMS BSE3729 mic on GPIO 35. But the I can’t get the Arduino mic example to work. I looked inside and I saw D1 at the enclosure mic hole which which seems to have a different purpose. I can’t find a mic on the schematic but I could have the wrong schematic or don’t know what the mic symbol looks like.
I searched this forum and found a mic+leds+FFT example but that didn’t work either.
Could someone provide a link to a schematic with a mic on it and give the ref designation to help me find it on the M5Stack Fire circuit board. If I can find it, I can get it to work.
Hi bobolink according to the github documentation page
The microphone is located on pin 34
I tested the vu meter in the Fire examples
and it worked fine, could you please test again using pin 34
and see whether it works, if not it could be a faulty microphone
Thank you. Will try pin 34.
