The M5Stack PDM Mini Unit is a digital MEMS SPM1423 microphone with PDM (Pulse Density Modulation). The microphone has a high signal-to-noise ratio, high sensitivity, low power consumption and a smooth frequency response. Automatically switches the microphone state according to the clock frequency (off, wake up, sleep). The module has a Grove connector (characteristic for M5Stack sets) with an I2S interface. It will be widely used in the area of audio data collection, eg in "wearable" devices or as a noise meter. Full documentation is available on the product page.
