Microphone coupon board based on the MP34DT04 digital MEMS microphone

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 X­NUCLEO­CCA02M1 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.

Key Features
