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","published_at":"2025-09-26T02:09:31+10:00","created_at":"2025-09-26T02:09:27+10:00","vendor":"Adafruit","type":"Microphone Elements","tags":["industryDE_Sep2025"],"price":13100,"price_min":13100,"price_max":13100,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":45747088294041,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"de-B01BU6YZ6M","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Adafruit Silicon MEMS Microphone Breakout - SPW2430","public_title":null,"options":["Default Title"],"price":13100,"weight":20,"compare_at_price":null,"inventory_management":"shopify","barcode":"603149690417","requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/soundstores.net\/cdn\/shop\/files\/de-B01BU6YZ6M.jpg?v=1775752792","\/\/soundstores.net\/cdn\/shop\/files\/51zWJb7wniL.jpg?v=1758816570","\/\/soundstores.net\/cdn\/shop\/files\/61G5WZ5MTPL.jpg?v=1758816569","\/\/soundstores.net\/cdn\/shop\/files\/51iiY159t0L.jpg?v=1758816569"],"featured_image":"\/\/soundstores.net\/cdn\/shop\/files\/de-B01BU6YZ6M.jpg?v=1775752792","options":["Title"],"media":[{"alt":"[AUSTRALIA] - Adafruit Silicon MEMS Microphone Breakout - SPW2430 ","id":34643404357785,"position":1,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/soundstores.net\/cdn\/shop\/files\/de-B01BU6YZ6M.jpg?v=1775752792"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/soundstores.net\/cdn\/shop\/files\/de-B01BU6YZ6M.jpg?v=1775752792","width":500},{"alt":"[AUSTRALIA] - Adafruit Silicon MEMS Microphone Breakout - SPW2430 ","id":34643404390553,"position":2,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/soundstores.net\/cdn\/shop\/files\/51zWJb7wniL.jpg?v=1758816570"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/soundstores.net\/cdn\/shop\/files\/51zWJb7wniL.jpg?v=1758816570","width":500},{"alt":"[AUSTRALIA] - Adafruit Silicon MEMS Microphone Breakout - SPW2430 ","id":34643404423321,"position":3,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/soundstores.net\/cdn\/shop\/files\/61G5WZ5MTPL.jpg?v=1758816569"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/soundstores.net\/cdn\/shop\/files\/61G5WZ5MTPL.jpg?v=1758816569","width":500},{"alt":"[AUSTRALIA] - Adafruit Silicon MEMS Microphone Breakout - SPW2430 ","id":34643404456089,"position":4,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/soundstores.net\/cdn\/shop\/files\/51iiY159t0L.jpg?v=1758816569"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/soundstores.net\/cdn\/shop\/files\/51iiY159t0L.jpg?v=1758816569","width":500}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eAdafruit Silicon MEMS Microphone Breakout - SPW2430\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eListen to this good news – we now have a breakout board for a super tiny MEMS\nMicrophone.
