STEVAL-MKI155V3 Datasheet, PDF (1/4 Pages) STMicroelectronics – 120 dBSPL acoustic overload point

STEVAL-MKI155V3
Microphone coupon board based on the MP34DT01-M digital
MEMS microphone
Data brief
Description
The STEVAL-MKI155V3 board is a
daughterboard to be used with the STEVAL-
MKI126Vx (Smart Voice) kit, containing 4
MP34DT01-M digital MEMS microphones.
The coupon concept allows easy performance
testing of ST MEMS microphones. When
connected to the Smart Voice board, it is possible
to detach the single PCBs hosting each
microphone.
