Microphone pinout

Can anyone confirm the I2S pinout used for the Proto Muse board, trying to see if this board will function as an ESPHome Assist board for Home Assistant

Looking for details similar to this:

i2s_lrclk_pin: GPIO33
i2s_bclk_pin: GPIO19


  • platform: i2s_audio
    id: echo_microphone
    i2s_din_pin: GPIO23

Thanks in advance.

Hi Zala. Take a look at this form post as it is covering hot to use the Muse Proto and the Muse Luxe with ESPHome as a Home Assistant voice assistant.but to answer your question more directly the yaml for ESPHome should be as follows (I don’t have a Muse Proto so I haven’t tested this, this is just according to the Muse Luxe setup and the pinout of the Muse Proto according to raspiaudio)


  • i2s_lrclk_pin: GPIO25
    i2s_bclk_pin: GPIO5


  • platform: i2s_audio
    id: proto_microphone
    i2s_din_pin: GPIO35
