How to connect the INMP441 (I2S microphone) to the M5Stack?
-
Hello everyone.
I´m doubt about which pins to use to connect the INMP441.
How to connect the components?
There are no I2S pins in ESP32. Instead, I need to set / enable the pins in code.
All examples use the I2S-MEMS to the following ESP32 pins:- SEL is unconnected, i.e. only one channel, apparently left
- LRCL to #15
- DOUT to #32
- BCKL to #14
- GND to GND
- 3V to 3V

INMP441
Technically all pins in an ESP32 are I2S.
Because of the amount of functions packed into the chip selecting pins and functions are separate things.
What M5Stack are you using?
What model INMP441 are you using as the pinouts dont match anything I can find. -
Thanks for your help.
M5Stack ESP32 MPU9250

I know I'm late to the game but I just bought one of these. Did you ever manage to connect it to your m5stack @dfabro ? if not I'm gonna try, and if I'm successful will post my findings here
