The STEVAL-STWINMAV1 microphone array expansion adds advanced audio sensing capabilities to the 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 batter-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 drivers and application examples for you to test and develop vibration monitoring in the ultrasound frequency ranges.主な特徴
