  • The STEVAL-MKI126V2 system evaluation board can connect up to six microphones using the sockets provided or through a dedicated six-microphone array.

    The digital interface of the device allows interfacing the MIC output to the most widely used audio receivers and digital amplifiers or simple evaluation of the MIC using generic audio measurement equipment. The filtered PWM signals allow the connection of a headset to listen to the audio received through the microphones.
    The fully digital path ensures a high level of processing with sound preconditioning, filtering and voice enhancement.
    The main purpose of the STEVAL-MKI126V2 is to convert the PDM signals provided by the microphones into the more common I2S and PWM signals. The I2S signal is routed both on general and interface connectors, while the suitably-filtered PWM signals provide an analog interface.
    Mounted on the STEVAL-MKI126V2 are two MP34DB01 microphones and an STA321MPL processor.
