製品概要
概要
The STEVAL-MKI129V5 daughterboard is designed to be used in conjunction with the STEVAL-MKI126V3 (STSmartVoice) or X-NUCLEO-CCA02M1, it contains 4 MP34DT05 digital MEMS microphones.
The coupon concept simplifies performance testing of the ST MEMS microphones. When attached to the X-NUCLEO-CCA02M1 board, it can export four additional PDMs for user application requirements (NBW algorithm detection).
When inserted in the STSmartVoice board, you can disconnect the single PCBs hosting each microphone.
