Datasheet

Upload to your Arduino Zero/Feather wired up as above, and open up the Serial Plotter

This example reads audio data from an I2S microphone

breakout board, and prints out the samples to the Serial console. The

Serial Plotter built into the Arduino IDE can be used to plot the audio

data (Tools -> Serial Plotter)

Circuit:

* Arduino/Genuino Zero, MKRZero or MKR1000 board

* GND connected GND

* 3.3V connected 3.3V (Zero) or VCC (MKR1000, MKRZero)

* WS connected to pin 0 (Zero) or pin 3 (MKR1000, MKRZero)

* CLK connected to pin 1 (Zero) or pin 2 (MKR1000, MKRZero)

* SD connected to pin 9 (Zero) or pin A6 (MKR1000, MKRZero)
