   "description": "Specifications Rated Voltage: 2.4-5.5V Application: Cellular phone,Microphone amplifier,Speech recogntion system Easy to use: Connect GND to ground, VCC TO 2.4-5VDC. For best performance, use \"The quietest\" Supply available (on an Arduino, this will be 3.3V) Wave sound Will Come OUT OUT PIN. The output will have DC. BIAS of VCC/2 so when Completely silent, the voltage will be constant VCC/2V (DC coupled). Requires an AC coupled audio, place a 100uF capacitor between the output PIN and the input of your device. If You connect an audio amplifier that has a differential input or includes a capacitor, 100uF cap is not required The output pin is not designed to drive speakers or anything, but is the smallest in headphones - you'll need sound amplifier (eg 3.7W stereo AMP) if you want to connect the AMP directly to the speaker. If Mr. Connect the microcontroller Pin, don't need amplifier or decoupling. Capacitor-Connect OUT Pin directly to the microcontroller ADC pin. For audio-reactive projects we recommend using the FFT DRIVER Library which can input audio and 'translate' as frequency More Information Same Spec Items - SKU A-7508 Manufacturer 100 Electronics MPN A-7508 Can be used with -",
