X-NUCLEO-CCA0M Digital MEMS microphones expansion board based on MPDT0-M for STM Nucleo Data brief Features x MPDT0-M Digital MEMS microphones on board slots to plug digital microphone coupon boards such as STEVAL-MKIVx and STEVAL-MKIVx Up to microphone synchronized acquisition and streaming Free comprehensive development firmware library and audio capture and USB streaming example application compatible with STMCube firmware Compatible with STM Nucleo boards Equipped with Morpho connector (upward and downward) Equipped with Arduino UNO R connector (upward) to allow multiple board application RoHS compliant Description The X-NUCLEO-CCA0M is an evaluation board based on digital MEMS microphones. It is compatible with the Morpho connector layout, and it's designed around STMicroelectronics MPDT0-M digital microphones. It has two microphones soldered on board and it is compatible with digital microphone coupon boards such as STEVAL-MKIVx and STEVAL-MKIVx. The X-NUCLEO-CCA0M allows the acquisition and streaming of up to microphones using the I²S peripheral and up coupon microphones using both I²S and SPI. It represents an easy to use and fast solution for the development of microphone based application as well as a starting point for audio algorithm implementation.
