X-NUCLEO-CCA02M1

X-NUCLEO-CCA02M1 Digital MEMS microphones expansion board based on MP34DT01-M for STM32 Nucleo Data brief Description 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. Features 2 on-board MP34DT01-M digital MEMS microphones 6 slots to plug in digital microphone coupon boards such as STEVAL-MKI129Vx and STEVAL-MKI155Vx Synchronized acquisition and streaming of up to 4 microphones Free comprehensive development firmware library and audio capture plus USB streaming sample application which is compatible with STM32Cube firmware Compatible with STM32 Nucleo boards Equipped with ST morpho connector (upwards and downwards) Equipped with Arduino UNO R3 connector (upwards) to allow multiple boards RoHS compliant January 2016 DocID027869 Rev 2 1/5 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagrams X-NUCLEO-CCA02M1 1 Schematic diagrams Figure 1: X-NUCLEO-CCA02M1 circuit schematic (Part 1) Figure 2: X-NUCLEO-CCA02M1 circuit schematic (Part 2) 2/5 DocID027869 Rev 2
