The MAX9814 Electret Microphone Amplifier Module captures sound and amplifies it with built-in Automatic Gain Control (AGC), so quiet and loud sounds stay clean without clipping. It delivers a ready-to-read analog audio signal to any Arduino analog pin, perfect for sound-reactive and voice projects.
Key Features
- Automatic Gain Control (AGC) keeps output steady across volume levels
- Analog audio output — connect straight to an analog input
- Selectable gain (40dB, 50dB, 60dB) and adjustable attack/release
- Low-noise electret microphone included on-board
- Works with Arduino, ESP32, ESP8266 and Raspberry Pi
