## Description

The Adafruit SPW2430 Silicon MEMS Microphone Breakout is a compact, low-cost microphone module that detects sound and converts it to an analog voltage — no external bias resistor or amplifier needed. With a frequency range of 100 Hz to 10 kHz, it's well suited for general-purpose audio recording, detection, and sound-reactive projects. The breakout provides both DC-coupled and AC-coupled outputs. The DC pin outputs the audio waveform with a 0.67 V bias (approximately 100 mVpp when speaking nearby, up to 1 Vpp for loud sounds). The AC pin includes a 10 µF series capacitor for equipment that requires AC-coupled audio input. Key Features SPW2430 MEMS Microphone – Built-in amplifier, no external bias or preamp needed Frequency Range – 100 Hz to 10 kHz DC & AC Outputs – DC pin with 0.67 V bias for direct ADC connection; AC pin with capacitor coupling Output Level – ~100 mVpp typical speech, up to 1 Vpp for loud sounds (line-level compatible) 3.3–5 V Power – Onboard 3 V regulator; best performance on a quiet 3.3 V supply Compact Size – Minimal board with just the mic, regulator, and filter capacitors Note: This breakout does not include an adjustable gain amplifier. The output is not designed to drive speakers or headphones directly — an external audio amplifier is needed for speaker output. For direct microcontroller ADC reading, connect the DC pin without any additional components. Ideal For Audio-reactive projects using FFT Voice changers and audio recording/sampling Sound level detection and monitoring Line-level audio input to recording equipment Package Contents 1× Adafruit SPW2430 Silicon MEMS Microphone Breakout
