M5Stack PDM Microphone Unit SPM1423 Pulse Density Modulation Signal Automatic Voice Recording Module Programmable Module

  • $20.99
  • Product Description

    Description:
    PDM mini Unit is a digital MEMS silicon-based microphone based on PDM (Pulse Density Modulation) signal. The microphone has 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 audio data collection on wearable devices and smart digital devices.
    Features:
    - I2S PORT,PDM encoding output (CLK/DAT)
    - High sensitivity, high signal to noise ratio
    - Low power consumption
    - Anti-radio frequency interference
    - Compatible with LEGO
    Package Included:
    - 1x PDM mini Unit
    - 1x HY2.0 4P Cable(5CM)
