MEMS microphone demonstration board based on the MP45DT02 and STM32 (STEVAL-MKI117V2)

The purpose of the STEVAL-MKI117V2 demonstration board is to provide an example of the decoding and streaming of digital MEMS microphone outputs.

The STEVAL-MKI117V2 demonstration board hosts the MP45DT02 (top-port digital microphone), working as a sensor, and the STM32F107RC microcontroller, working as an audio decoder.

These microphones are analog-to-digital transducers, in other words, they are able to sense sound pressure and convert this signal into a digital signal using the PDM technique.

The STM32 microcontroller decodes the PDM signal coming from the microphones and streams the audio via the USB.

The STEVAL-MKI117V2 demonstration board is a sound card automatically recognized by the PC as an audio device. The connection is made through a USB cable which also supplies the board and then streams the collected audio.

Возможности

  • Powered and connected to PC through USB
  • Sound card automatically recognized by the PC as an audio device
  • The onboard microphones are digital MEMS devices
  • MEMS microphones provide a high frequency data stream (1 to 3.25 MHz) of 1-bit digital samples (PDM technique)
  • Audio collected from the microphones is sent to the PC through the USB
  • LED status indicator
  • RoHS compliant
