2 STCK. GY-SPH0645 I2S MEMS Mikrofon Breakout Sensor Modul für Arduino
11,02 €
It's a 1.6-3.6V max device only, so not for use with 5V logic (its really unlikely you'd have a 5V-logic device with I2S anyways). You can select whether you want it to be on the Left or Right channel by connecting the Select pin to power or ground.
