STEVAL-MKI139V4
Microphone coupon board based on the MP23AB01DH analog
MEMS microphone
Data brief
Description
The STEVAL-MKI139V4 board contains four
MP23AB01DH analog MEMS microphones.
The coupon design allows easy performance
testing of STM MEMS microphones, with the
possibility of detaching the single PCBs hosting
each microphone.
