Description
The STEVAL-MKI129V4 is a daughterboard
designed to be used in conjunction with the
STEVAL-MKI126Vx (Smart Voice) kit, containing
four MP34DT04 digital MEMS microphones.
The coupon concept allows easy performance
testing of the ST MEMS microphones.
When plugged into the X-NUCLEO-CCA02M1
expansion board, it is able to export the four
additional PDM for any need (NBW algorithms
detection).
When plugged into the Smart Voice board, it is
possible to detach the single PCB hosting each
one.
