M5 Stack PDM Microphone Unit (SPM1423) Intermediate Kits It encodes the 12 bitM5 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
