產品概述
STEVAL-MKI116V1 demonstration board is to provide an example of the decoding and streaming of digital MEMS microphone outputs. Board hosts the MP34DB01 (bottom port digital microphone), working as a sensor, and the STM32F107RC microcontroller, working as an audio decoder. These microphones are analogue to digital transducers. 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. This board is a sound card automatically recognized by the PC as an audio device. Connection is made through a USB cable which also supplies the board and then streams the collected audio.
- 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 (1MHz to 3.25MHz) of 1bit digital samples
- Audio collected from the microphones is sent to the PC through the USB
LED status indicator
Applications
- Audio, Consumer Electronics, Portable Devices, Imaging, Video & Vision, Security
