A digital audio sensor designed for sound capture in microcontroller-based projects. By providing a direct I2S (Inter-IC Sound) output, this module translates acoustic waves into digital data without the need for external pre-amplifiers or bulky analog-to-digital converters.

Traditional analog microphones often suffer from signal degradation and electrical noise, especially when routed near Wi-Fi antennas or motor controllers. This MEMS unit eliminates these frustrations by performing the analog-to-digital conversion directly on-chip, delivering a clean, noise-resistant signal straight to your dev-board using a universal protocol.

Features

Enjoy interference-free audio by utilising a direct digital I2S output that bypasses the hiss and hum of noisy analog-to-digital conversion stages.
Capture crystal-clear voice commands and subtle environmental sounds with a high 61 dB(A) signal-to-noise ratio, providing the clarity needed for speech recognition algorithms.
Simplify your power budget with an ultra-efficient design that draws less than 2mA of current, making it perfect for "always-on" listening in portable projects.
Integrate with ease into 3.3V logic systems, ensuring direct compatibility with modern development boards without the need for level shifting.
