DFSDM microphones module (MB1299)

7.2.1

Description

A DFSDM Beam Forming microphone module (MB1299) can be connected to STM32H7B3LIH6QU DFSDM
interface through CN4.
MB1299 module embeds five DFSDM MEMS microphones STMicroelectronics MP34DT01TR-M:
•

One microphone for detection in the center (CLK_0, DATA_0)

•

Four other microphones for beamforming (CLK_1, DATA_1, and DATA_3)
