It combines an electret microphone with a dedicated low-noise amplifier circuit on a small breakout board, making it easy to integrate sound sensing into custom designs.\u003c\/p\u003e\n\u003cp\u003eThis module is commonly used in projects that require detection or analysis of ambient audio signals. Typical use cases include sound-reactive lighting, voice-triggered controls, audio level monitoring, and basic audio input for microcontrollers. The amplified analog output allows sound signals to be processed by ADC pins or further signal-processing circuits.\u003c\/p\u003e\n\u003cp\u003eA key benefit of this module is the onboard adjustable gain control. The small trim potentiometer allows users to fine-tune amplification levels based on input sound strength and application requirements. This helps achieve clear signal output while reducing distortion or noise caused by excessive gain.\u003c\/p\u003e\n\u003cp\u003eThe module operates on a low DC supply voltage, making it suitable for battery-powered systems and common development boards. Its analog output includes a DC bias, which is useful for direct connection to microcontroller analog inputs without additional circuitry in many cases.\u003c\/p\u003e\n\u003cp\u003eDesigned for hobbyists, students, and developers, this electret microphone amplifier is compatible with a wide range of audio sensing and embedded applications. Its small size and simple three-pin interface make it easy to use in prototypes, educational projects, and compact electronic builds.\u003c\/p\u003e\n\u003cp\u003eThe package includes one MAX4466 Electret Microphone Amplifier module with the microphone and components pre-mounted on the PCB.\u003c\/p\u003e\n\u003cp\u003eSPECIFICATIONS\u003cbr\u003eProduct Type : Electret microphone amplifier module\u003cbr\u003eAmplifier IC : MAX4466\u003cbr\u003eMicrophone Type : Electret condenser microphone\u003cbr\u003eOperating Voltage : 2.4 V to 5.5 V DC\u003cbr\u003eOutput Type : Analog audio signal\u003cbr\u003eGain Control : Onboard adjustable trim potentiometer\u003cbr\u003eOutput Bias : Approximately VCC \/ 2\u003cbr\u003eConnection Pins : VCC, GND, OUT\u003cbr\u003eMounting Type : PCB breakout module\u003cbr\u003ePCB Size : Compact form factor\u003cbr\u003eApplication Type : Audio sensing and signal amplification\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eKEY FEATURES\u003cbr\u003e- Uses MAX4466 low-noise microphone amplifier IC\u003cbr\u003e- Integrated electret microphone mounted on breakout board\u003cbr\u003e- Adjustable gain via onboard trim potentiometer\u003cbr\u003e- Analog audio output with DC bias\u003cbr\u003e- Low voltage operation for embedded electronics\u003cbr\u003e- Compact PCB suitable for space-constrained designs\u003cbr\u003e- Three-pin connection interface for easy wiring\u003cbr\u003e\u003c\/p\u003e","brand":"MAJESTRONICZ","offers":[{"title":"Default Title","offer_id":46511562227870,"sku":null,"price":120.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/9257\/2574\/files\/MAX4466ElectretMicrophoneAmplifierimg1.jpg?v=1770979636","url":"https:\/\/majestronicz.in\/products\/max4466-electret-microphone-amplifier-module-with-adjustable-gain","provider":"MAJESTRONICZ","version":"1.0","type":"link"}
