STEVAL-MKI155V1
Microphone coupon board based on the MP45DT02-M digital
MEMS microphone
Data brief
Description
The STEVAL-MKI155V1 board is a
daughterboard to be used with the STEVAL-
MKI126Vx (Smart Voice) kit, containing 4
MP45DT02-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.
Features
 4 x MP45DT02-M top port digital MEMS
microphones
