Product Overview

STEVAL-MKI138V1 is to provide a demonstration of decoding and streaming of digital MEMS microphone outputs. The STEVAL-MKI138V1 demonstration board hosts the MP34DT01 (top port digital microphone), working as a sensor and the STM32F107RC microcontroller, which functions as an audio decoder. These microphones are analogue to digital transducers. They are capable of sensing sound pressure and converting it to a digital signal using the PDM technique. The STM32 microcontroller decodes the PDM signals from the microphones and streams the audio via USB. The STEVAL-MKI138V1 is a sound card automatically recognized by the PC as an audio device. Connection is made through a USB cable, which both powers the board and streams the audio collected from the microphones to the PC.
  • Powered and connected to PC through USB
  • Sound card automatically recognized by the PC as an audio device
  • MEMS microphones provide a high frequency data stream (1MHz to 3.25MHz) of 1bit digital samples
  • Audio collected from the microphones is sent to the PC through USB
  • LED status indicator

Applications

Audio, Consumer Electronics, Portable Devices, Imaging, Video & Vision, Security
