2.1 Hardware description
This section describes the hardware components needed for developing a sensors based
application.
2.1.1 STM32 Nucleo platform
The STM32 Nucleo boards provide an affordable and flexible way for users to try out new
ideas and build prototypes with any STM32 microcontroller lines. The Arduino™
connectivity support and ST morpho headers make it easy to expand the functionality of
the STM32 Nucleo open development platform with a wide range of specialized expansion
boards to choose from. The STM32 Nucleo board does not require any separate probe as
it integrates the ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo board comes
with the comprehensive STM32 software HAL library together with various packaged
software examples.

2.1.2 X-NUCLEO-CCA02M1 expansion board
The X-NUCLEO-CCA02M1 is an evaluation board based on digital MEMS microphones. It
is compatible with the morpho connector layout, and is designed around
STMicroelectronics’ MP34DT01-M digital microphones. There are two microphones
