What is it?

A really nice and small breakout board for the ICS-43434 I2S MEMS microphone from InvenSense. This replaces the INMP441 and the ICS-43432. The INPM441 is no longer recommended for new designs and the ICS-43432 is superseded by this new microphone.

These are great devices that you interface directly to your microcontroller without needing any analog to digital converters.

Why did you make it?

I've been doing a lot of projects recently getting audio into the ESP32 and wanted a board that used the latest microphone. The boards that are easily available are either based on the INMP441 which is out of date or the SPH0645LM4H which has issues with the ESP32 due to I2S timing incompatibilities.

What makes it special?

It's really easy to wire up to the ESP32 with all the pins broken out on one side of the board. I2S is a really nice interface for audio as you don't need to use any ADC - which on the ESP32 is not very good!

Nice little board that does exactly what I needed

The ICS-43434 Chip has significantly better specs than its predecessor or similar MEMS microphones.
There just aren’t many breakout-boards available (at a reasonable price).
This board is just perfect. No nonsense, just the required components which make it possible to interface with, for example an ESP32 board.

Ordering and shipping went smoothly. Shipping did take approximately a week, but that’s to be expected with UK-EU mail deliveries nowadays.

Excellent product, great service

The product performed exactly as identified. High quality board. Seller was responsive on my follow up questions.
Highly recommended.

Better than I expected

Not cheap but it is worth every penny.
Very clear sound.
No issues during setup. Clear documentation.

Great product, quick delivery

Very well executed. Follow the provided instructions and run the code and everything should work fine. I really like this mic which outputs great sound. A must for esp32 (and others) projects requiring voice. Atomic14 also has great youtube videos for integrating the mic with projets requiring voice recognition and wake-word detection.
