Description

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 sensitivity and high signal-to-noise ratio
• Low power consumption
• Strong RF interference immunity
• LEGO-compatible

Includes

• 1 x Unit Mini PDM
• 1 x HY2.0-4P Grove Cable (5cm)

Applications

• Spectrum analyzer
• Audio recording
• Sound level meter
