## Overview

The INMP441 is a high-precision MEMS omnidirectional microphone module featuring a digital 24-bit I2S interface, ultra-low 1.4mA power consumption, and a compact 14x12x2mm form factor. Designed for seamless integration with ESP32 and similar microcontrollers, it delivers crystal-clear audio with a 61 dB signal-to-noise ratio and a wide frequency response from 60 Hz to 15 kHz, making it the go-to choice for professional-grade DIY audio projects.

## Description

Product Features: 1. Digital I2S interface with high precision 24-bit data 2. High signal to noise ratio is 61 dBA 3. High sensitivity - 26 dBFS 4. Stable frequency response from 60 Hz to 15 kHz 5. Low power consumption: low current consumption 1.4 mA 6. 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.

Connect to ESP32: INMP441 SCK >> GPIO14 SD >> GPIO32 WS >> GPIO15 L/R >> GND GND >> GND VDD >> VDD3.3 Package includes: 5pcs x Microphone module

Review: Great quality - The little mic that hears it all—literally. With its I2S interface and high precision, it’ll pick up every whisper, hum, and sneeze in the room. Perfect for your DIY projects, just be careful—it’s so sensitive, it might even catch your dog’s secret plans to steal dinner!
Review: These mics work great AS LONG AS YOU SOLDER THE RIGHT SIDE! - These are great mics. I tested a number of analog and digital mics, researched other people's recommendation, and tried a number. This is the best sounding mic for stereo audio capture with a microcontroller I have found. Beware to take care soldering because I ruined a bunch of these by soldering them incorrectly. Look closely at the center of the breakout board in the image. These are both from this product. There's a strange instinct to solder the headers with the chip on top and the flat section on the bottom. Problem is the mic is the hole on the side without the chip. If you solder the chips on wrong side, like i did 4 times, the mic is effectively blocked by the breadboard, permaproto or other installation. I've found a way to use some of my bad ones without desoldering by using female header pins and finding a way to allow sound to reach the mic hole, but this isn't going to work for many use cases. Therefore solder them correctly with the mic hole up and the pins pointing down. Furthermore, I can't recall any of the product pages for INMP441 mentioning the soldering problem. I googled it and found I was far from alone making this mistake. EDIT: I gave them the full 5 stars after trying other brands and finding none handled the correct soldering issue and this brand seemed highest quality with prime deliver. Frankly the Teyleten Robot INMP441 Omnidirectional Microphone Module MEMS High Precision Low Power 3-pack would get 5 stars if not for them being on the expensive side and for the fact that there was nothing in the packaging that I recall that would have helped me avoid wasting 4. I also tried some from aliexpress and other mems, pdm digital mics. These do not require an analog input on the CPU or MCU. They utilize standard digital pin protocols. You'll need power, ground, and 3 GPIO pins. This is more complex than an analog mic such as MAX4466 which requires +, -, and an analog input pin, 2 pins less than Mems or other 3 wire protocols. But let me tell you something. The audio captured by a properly soldered INMP441 is about 10 times clearer and more representative of the actual sound being recorded. Write a small Python, CircuitPython, or C/Arduino program to do nothing but record into a buffer big enough to fit 10 seconds of sound. Then render the sound from each mic. I am positive you will select the INMP441. It's a very capable, affordable, well supported, and consistent quality. If you don't want to waste your time testing and trial and error like I did, just buy these. I need to find a similar quality vendor as Teyleten Robot or a way to buy these in bulk over aliexpress perhaps since this is now my electronics product mic of choice for voice capture, or sound reactive algorithms. In my attached photo, I put two of these side by side. The green arrow points to the correctly soldered and working mic, the red arrow is a fail. Again, I do trust this brand and will buy again. I'm just mad about no warning about soldering the headers!

## Questions & Answers

**Q: So am i supposed to connect the l/r and gnd pins of the inmp4441 to the same gnd pin on the esp32?**
A: Dear fellow. There is just one ground on any device, or processor, including ESP32. You may connect any number of devices to that ground.

### ⭐⭐⭐⭐ works nicely with ESPHome voice assistant
*by E***O on 13 November 2023*

purchased for a ESPHome voice assistant project, works quite well.. just remember to pull the L/R pin high or low, don't leave it floating or you will have issues!
