Your cart is empty. Digital I2S interface with high precision 24-bit data
High signal to noise ratio is 61 dBA
High sensitivity - 26 dBFS
Stable frequency response from 60 Hz to 15 kHz
Low power consumption: low current consumption 1.4 mA
High PSR: -75 dBFS
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
This product provides tutorials for using ESP32 modules with I2S functionality.
Connect to ESP32:
INMP441 ESP32
SCK >> GPIO14
SD >> GPIO32
WS >> GPIO15
L/R >> GND
GND >> GND
VDD >> VDD3.3
Package include:
3 x INMP441 omnidirectional microphone module

Wired these up to several ESP32 to add sound reactive lights to WLED. They work well and are easy to use

This is a very small device and greatly exceeds the performance of a passive microphone. With appropriate driving software that performs AGC, this microphone works extremely well and is ultra sensitive. A little tricky to solder since the connections are so small. Great buy!

I've gone through the trouble of solding the pins in place and plan to incorporate it into an LED controller so it will have music syncing capabilities, but for whatever reason, when I gather up my breaboard, dupont wires, controller, with the intent to program it all, I never quite make it that far. still all stabbed into my breadboard and staring at me when I'm within reach, but seems I always have more pressing things going on. I'll get to it, I swear. Soon as this other stuff is done. (hopefully before new, more pressing stuff comes up. Fat chance, but one can hope. lol Such is foodtruck life. It's ALWAYS somethin'.)

Unsure on audio quality, but these worked great for my sound-reactive WLED project.

If you are making an audio reactive display with WLED, these are very good!
