X-NUCLEO-CCA02M2 Hardware Description
The X-NUCLEO-CCA02M2 expansion board has been designed around MP34DT06J digital MEMS microphone. It is
compatible with the ST morpho connector layout and with digital microphone coupon boards such as STEVAL-
MIC001V1, STEVAL-MIC002V1 and STEVAL-MIC003V1.
The X-NUCLEO-CCA02M2 embeds two MP34DT06J microphones and allows synchronized acquisition and
streaming of up to 4 microphones through I²S, SPI, DFSDM or SAI peripherals.
