• STEVAL-STWINMAV1 microphone array expansion board

The STEVAL-STWINMAV1 microphone array expansion adds advanced audio sensing capabilities to the STEVAL-STWINKT1B (and STEVAL-STWINKT1) Sensor Tile 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.

Features:

  • Analog microphone array expansion for STEVAL-STWINKT1B (and STEVAL-STWINKT1)
  • Connects to STWIN core system board through dedicated 12-pin connector
  • 3 V to 5.5 V power supply input
  • 4 mm square-shaped differential microphone array
  • 4x MP23ABS1 high-performance, single-ended, analog, bottom-port MEMS microphones
  • LDK130 300 mA low quiescent current very low noise LDO
  • On-board audio-grade quad ADC
  • Serial Audio Interface (SAI) digital output
