Enjoying this mic
The performance of this mic has been great. I'm using it on an ESP32 with WLED Sound Reactive. The sensitivity of the mic had been great. Picks up sounds really well.

- This is INMP441 MEMS High Precision Omnidirectional Microphone Module I2S
- It includes a complete solution with a MEMS sensor, signal conditioning, and analog to digital converter, among other components.
- The I2S interface allows for direct connection to digital processors without the need for an audio codec.
- The INMP441 has a high signal-to-noise ratio of 61 dBA, making it great for applications in close proximity.
- It has a flat wideband frequency response, resulting in natural and high-definition sound.
- The microphone has a low power consumption, with a current consumption of 1.4 mA.
- The INMP441 also has a high PSR of -75 dBFS, ensuring stable performance.
INMP441 MEMS High Precision Omnidirectional Microphone Module I2S
The INMP441 is a digital MEMS microphone that is omnidirectional and has a bottom port. It is designed to be high-performing and low-power, and the complete solution includes a MEMS sensor, signal conditioning, analog to digital converter, anti-aliasing filter, power management, and a 24-bit I2S interface that is industry-standard.
The I2S interface is especially useful because it allows for direct connection to digital processors such as microcontrollers and DSPs without the need for an audio codec. With a high signal-to-noise ratio, the INMP441 is a great option for applications in close proximity. It also has a flat wideband frequency response that results in natural and high-definition sound.
Interface definition
- SCK: Serial data clock for I2S interface
- WS: Serial data word selection for I2S interface
- L/R: Left/Right channel selection.
- When set to low, the microphone outputs a signal on the left channel of the I2S frame.
- When set to high level, the microphone outputs signals on the right channel
- SD: Serial data output of the I2S interface.
- VCC: Input power, 1.8V to 3.3V.
- GND: power ground
