M5 Stack PDM Microphone Unit (SPM1423) PDM mini Unit is a digital MEMS silicon-based microphone based on PDM (Pulse Density Modulation) signal. The microphone has a high signal-to-noise ratio, high sensitivity, low power consumption, anti-radio frequency interference, smooth frequency response, and other characteristics. It automatically switches the microphone state according to the clock frequency (power down/activate/sleep)and can be widely used for the audio data collection on wearable devices and smart digital devices. Applications: Spectrum Analyzer Recorder Noise meter
