It amplifies microphone-level audio signals and features built-in Automatic Gain Control (AGC) with three selectable gain levels — 40dB, 50dB, and 60dB. It is commonly used in DIY electronics, voice recognition projects, audio recording systems, and embedded computing projects with boards like Arduino and ESP8266.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I connect the MAX9814 module to my development board (e.g., Arduino or ESP8266)?\u003c\/h4\u003e\n\u003cp\u003eA: The MAX9814 module connects directly to your microcontroller via its VCC, GND, and OUT (analog output) pins. Connect VCC to your board's 3.3V or 5V power rail, GND to ground, and OUT to an analog input pin on your development board. No additional adapters are required, making integration straightforward for most common platforms.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I change the gain setting on the MAX9814 module?\u003c\/h4\u003e\n\u003cp\u003eA: The gain is selected by connecting the GAIN pin on the module to different reference levels.
