Microphone Module Omnidirectional I2S Interface S With Pins INMP441

Feature:

1. The microphone module has a 24‑bit digital I2S interface with high‑ data, and the output performance is stable.
2. With flat broadband frequency response and high signal‑to‑noise ratio, it can produce high‑definition natural sound.
3. INMP441 is a high-performance, low-power, digital output omnidirectional MEMS microphone with a bottom port.
4. With MEMS sensor, signal conditioning, analog‑to‑digital converter, anti‑aliasing filter, power management and I2S interface.
5. The microphone outputs the signal on the left channel when the level is low, and outputs the signal on the right channel when the level is high.
