Just like \u0026amp;  39; classic \u0026amp;  39; Electret Microphones, MEMS\nmicrophones can detect sound and convert it to voltage, but they don \u0026amp;  39; t\nneed a bias resistor or amplifier, its all in one. The SPW2430 is a small, low\ncost MEMS MIC WITH A RANGE OF 100 Hz – kHz, good for just about all general\naudio recording\/motion detection. This breakout is best used for projects such\nas voice changers, audio recording\/sampling, and audio reactive projects that\nuse FFT. To keep the breakout Small and simple, we only added a 3 V Voltage\nRegulator (the microphone requires 3.3 V DC) and filter capacitors. No\nadditional opamp is included, the output peak to peak output voltage has a\n0.67 V DC bias and about 100mVpp (peak to peak) when talking near the\nmicrophone, which is good for attaching to something that expects \u0026amp;  39; LINE\nLEVEL \u0026amp;  39; Input without clipping. The peak to peak output can be as high\nas 1Vpp if there \u0026amp;  39; s a very loud sound. If you are if you need a\nmicrophone with adjustable gain or auto gain control, check out our mic +\namplifier options. If you need a higher peak to peak, a rail to rail op amp\nand some resistors can get you boosted up. 'Using it is simple: Connect GND to\nground, Vin to 3.3 – 5Vdc. For the best performance, use the \"quietest supply\navailable (on an Arduino, this would be the 3.3 V supply). The audio waveform\nwill come out of the DC pin. The output will have a DC bias of 0.67 V so when\nits perfectly quiet that \u0026amp;  39; s what you \u0026amp;  39; ll read, there \u0026amp;  39; s a\nlittle drift. If the audio equipment you \u0026amp;  39; re using requires AC coupled\naudio, you can grab the signal out of the AC Pin, which has a 10uF Capacitor\nin series. The output pin is not designed to drive speakers or anything but\nthe smallest in-ear headphones – You \u0026amp;  39; ll need to audio amplifier such\nas our 3.7 W stereo amp), if you want to connect the amp directly to speakers.\nIf you \u0026amp;  39; re con\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eAdafruit part number: 2716\u003c\/li\u003e\n         \u003cli\u003eStock Type: Sensor \u0026gt; \u0026gt; sound noise\u003c\/li\u003e\n         \u003cli\u003eStock in the UK\/European Lager\u003c\/li\u003e\n         \u003cli\u003eIn stock \u0026amp; ready to send\u003c\/li\u003e\n         \u003cli\u003eFree shipping\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":45747088294041,"sku":"de-B01BU6YZ6M","price":131.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0491\/3148\/7385\/files\/de-B01BU6YZ6M.jpg?v=1775752792","url":"https:\/\/soundstores.net\/products\/adafruit-silicon-mems-microphone-breakout-spw2430","provider":"SoundStore Australia","version":"1.0","type":"link"}
