X-NUCLEO-CCA02M1
Digital MEMS microphones expansion board based on MP34DT01-M for STM32 Nucleo.

The X-NUCLEO-CCA02M1 is an evaluation board based on digital MEMS microphones

It is compatible with the ST morpho connector layout, and is designed around STMicroelectronics MP34DT01-M digital microphones. It has two microphones soldered onto the board and is compatible with digital microphone coupon boards such as STEVAL-MKI129Vx and STEVAL-MKI155Vx.

The X-NUCLEO-CCA02M1 allows synchronized acquisition and streaming of up to 4 microphones through IS, SPI or DFSDM peripherals. It represents a quick and easy solution for the development of microphone-based applications as well as a starting point for audio algorithm implementation.
