STEVAL-MKI155V3
Microphone coupon board based on the MP34DT01-M digital MEMS microphone

The STEVAL-MKI155V3 board is a daughterboard to be used with the STEVAL-MKI126Vx (Smart Voice) kit, containing 4 MP34DT01-M digital MEMS microphones.

The coupon concept allows easy performance testing of ST MEMS microphones. When connected to the Smart Voice board, it is possible to detach the single PCBs hosting each microphone.
