Microphone coupon board based on the MP45DT02 digital MEMS microphone




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.
