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 The INPM441 is no longer recommended for new designs and the ICS-43432 is superseded by this new microphone.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.
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 The boards that are easily available are either based on the INMP441 which is out of date or the SPH0645LM4H which has issues with the ESP32 due to I2S timing incompatibilities.
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!
