soldered onto board and it offers the possibility to plug in additional microphones using
MP32DT01-based coupon evaluation boards (e.g. STEVAL-MKI129V3).
The X-NUCLEO-CCA02M1 allows the acquisition of up to two microphones using the I²S
bus and up to four coupon microphones using I²S and SPI together. In addition, it offers a
USB output for the STM32 Nucleo board. It represents a fast and easy solution for the
development of microphone-based applications as well as a starting point for audio
algorithm implementation.
