Analog microphone array board for advanced audio sensing

27 October 2021 Computer/Embedded Technology

The STEVAL-STWINMAV1 microphone array expansion board adds advanced audio sensing capabilities to STMicroelectronics’ STEVAL-STWINKT1B (and STEVAL-STWINKT1) SensorTile Wireless Industrial Node (STWIN) kit for high-frequency vibration monitoring applications.

The board includes four low-power, high signal-to-noise ratio (SNR) MP23ABS1 capacitive sensing microphones, supported by a very low drop voltage, low quiescent current and low-noise voltage regulator ideal for battery-powered applications such as STWIN.

The expansion board is connected via a dedicated 12-pin connector to the core system board, which runs the STSW-STWINKT01 firmware with dedicated BSP (board support package) drivers and application examples to test and develop vibration monitoring in the ultrasound frequency ranges.
