STEVAL-MKI139V3
Microphone coupon board based on the MP23AB02B analog
MEMS microphone
Data brief
Description
The STEVAL-MKI139V3 is a daughterboard
containing 4 MP23AB02B analog MEMS
microphones. The coupon concept allows easy
performance testing of ST MEMS microphones. It
is possible to detach the single PCBs hosting
each microphone.
