Module robotics: audio; microphone; I2S; IC: INMP441; SNR: 61dB

The OKY3139 is a high-performance, low-power omnidirectional MEMS microphone module with a digital output. Based on the INMP441 chip, it provides a complete audio capture solution for direct integration with digital processors.

Key Features
- Features a bottom-port, omnidirectional MEMS sensor for capturing sound from all directions.
- Equipped with a standard 24-bit I2S interface for direct connection to microcontrollers and DSPs, eliminating the need for a separate audio codec.
- Delivers a high signal-to-noise ratio (SNR) for exceptionally clear audio capture.
- Provides a flat, wideband frequency response, ensuring high-definition and natural-sounding audio reproduction.
- Designed for low power consumption, making it suitable for battery-powered devices.

Applications
With its high signal-to-noise ratio and clear sound reproduction, this module is an excellent choice for near-field audio recording applications where clarity and natural sound are essential.
