STEVAL-MKI139V1
Microphone coupon board based on the MP33AB01 analog MEMS
microphone
Data brief
Description
The STEVAL-MKI139V1 is a daughterboard
containing 4 coupon with the MP33AB01 analog
MEMS microphone.
The coupon concept allows to easily test the
performances of STM MEMS microphones, it is
possible to detach the single PCBs hosting a
single microphone.
