Microphones

Choose between a microphone preamp for analog audio sampling and a sound detector module for threshold/noise sensing.

Analog microphone preamp

Mic preamp → ADC waveform

MAX4466 electret microphone amplifier for sampling an analog audio waveform. Good for FFT, recording and audio-reactive effects when your ADC and software are ready for it.

Sound threshold detector

AOUT + DOUT threshold

LM386 sound sensor with analog sound output and a digital threshold pin. Good for simple noise/clap detection and relative sound activity.

Can I swap these?

Pick the board you have - we'll show what we know about swapping it.

Known swap options (1)

General board checks (5)
  • Do you need a continuous analog waveform, or only sound-present / louder-than-threshold detection?
  • Check whether the receiving board expects a biased analog signal, a threshold digital input, or an AC-coupled audio input.
  • Confirm supply voltage, ADC range and gain setting before swapping modules.
  • For dB readings, add calibration or use a sound-level sensor intended for that job.
  • Check mounting, microphone direction and noise from nearby motors/regulators.
