The SPW2430 MEMS microphone breakout board offers seamless integration for capturing sound with no bias resistor or amplifier needed. It mirrors traditional electret microphones by converting sound to voltage, covering a dynamic range from 100Hz to 10KHz. Ideal for various audio projects such as voice changers, audio-sampling, and FFT-based audio-reactive projects.Specifications include a built-in 3V voltage regulator and filter capacitors, but exclude an opamp for a streamlined design. The microphone outputs at 0.67V DC bias and about 100mV peak-to-peak when spoken into, rising to 1V peak-to-peak at higher volumes. It connects readily to devices expecting line-level input without causing distortion.Usage is straightforward; connect Ground to GND, and 3.3-5VDC to Vin. Utilize the quietest power supply available for optimal performance. The audio output is accessible via the DC pin, with an option to obtain AC-coupled audio from the AC pin. External amplification is necessary for driving speakers, while direct connection to microcontroller ADC pins is supported without additional components. https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2025-11-01 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2025-12-19 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-01-23 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-01-29 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-02-01 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-03-15 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-03-17 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-04-08 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-04-15 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-04-25 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-05-03 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-05-15 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-07-01 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-07-18 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-07-23 https://elecena.pl/product/29469746/adafruit-silicon-mems-microphone-breakout-spw2430 2026-08-02
