Microphone Coupon Board based on the MP45DT02 Digital MEMS Microphone
Manufactured By:ST Microelectronics




Part Number:STEVAL-MKI129V1
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.
The MP45DT02 is a compact, low-power, top-port, omnidirectional, digital MEMS microphone. The MP45DT02 is built with a sensing element and an IC interface with stereo capability. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process to produce audio sensors.
