<![CDATA[[Solved]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.

Thanks

Thank you. Will try pin 34.

https://m5stack.github.io/m5-docs/#/en/product_documents/m5stack-core/m5core_fire

The microphone is located on pin 34

I tested the vu meter in the Fire examples
https://github.com/m5stack/M5Stack/tree/master/examples/Fire/M5StackFire_NeoPixelVUmeter

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

Thanks
