Description
The STEVAL-MKI129V1 is a daughterboard
designed to be used in conjunction with the
STEVAL-MKI126Vx (Smart Voice) kit, containing
4 MP45DT02 digital MEMS microphones.
The coupon concept allows easy performance
testing of ST MEMS microphones. When inserted
in the Smart Voice board, it is possible to detach
the single PCBs hosting each microphone.
