Adafruit Silicon MEMS Microphone Breakout - SPW2430 PRODUCT ID 2716 Listen to this good news - we now have a breakout board for a super tiny MEMS microphone. Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they don't need a bias resistor or amplifier, its all in one! The SPW2430 is a small, low cost MEMS mic with a range of 100Hz - 10KHz, good for just about all general audio recording/detection. This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT. To keep the breakout small and simple, we only added a 3V voltage regulator the microphone requires 3.3V DC and filter capacitors. No additional opamp is included, the output peak-to-peak voltage has a 0.67V DC bias and about 100mVpp peak-to-peak when talking near the microphone, which is good for attaching to something that expects 'line level' input without clipping. The peak-to-peak can be as high as 1Vpp if there's a very loud sound. If you are If you need a microphone with adjustable gain or auto-gain control, check out our mic+amplifier options. If you need a higher peak-to-peak, a rail-to-rail op-amp and some resistors can get you boosted up! Using it is simple connect GND to ground, Vin to 3.3-5VDC. For the best performance, use the "quietest" supply available on an Arduino, this would be the 3.3V supply . The audio waveform will come out of the DC pin. The output will have a DC bias of 0.67V so when its perfectly quiet that's what you'll read, there's a little drift. If the audio equipment you're using requires AC coupled audio, you can grab the signal out of the AC pin, which has a 10uF capacitor in series. The output pin is not designed to drive speakers or anything but the smallest inear headphones - you'll need an audio amplifier such as our 3.7W stereo amp if you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin, you don't need an amplifier or decoupling capacitor - connect the DC pin directly to the microcontroller ADC pin. 9/30/2015 Technical Details Weight 0.9g Product Dimensions 15.8mm x 14.1mm x 2.9mm / x
