Access to on-board speaker and microphone?

orm-github opened this issue · comments

Hello,
Which GPIO's of the ESP32 are used to access and receive sound from the microphine and modulate/control the on-board speaker?

Also, I am considering adding an I2C based BME680 Temp/Humidity/Pressure/Gas sensor, are there any convenient was to get access to unused GPIO's without soldering directly to ESP32 module?

Thanks, in advance, for any help!

Did you ever find the ports for the microphone and / or speaker?

According to this reddit post:

MIC is on GPIO 39 ADC1_3. Looks like it's an analog mems that's not i2s.

Adding to what's already been said, as far as I am aware, there is no speaker on the pixel kit, only a microphone. Also, you might be able to use some USB-to-serial dongle or such for the sensor, as there should be some way to access the USB ports on the top of the kit using micropython. Other than that, there's no pins or ports to plug into, so you'll probably just have to find a free GPIO pin and solder to it.
