PDM MEMS Microphone Unit (SPM1423)

Unit Mini PDM is a digital MEMS silicon microphone based on PDM (Pulse Density Modulation) signals. It features high signal-to-noise ratio, high sensitivity, low power consumption, strong RF interference immunity, and smooth frequency response. The microphone automatically switches states (power-off / active / sleep) according to the clock frequency, making it suitable for audio data acquisition in wearable devices and smart digital devices. Features PDM signal output (CLK/DAT) High… (M5Stack U089)
