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)
Applications:
- Spectrum Analyzer - Recoder - Loudness meter
