MAX4466 Electret Microphone Amplifier Breakout Board – fully assembled module with onboard 20Hz–20kHz electret mic, adjustable gain trimmer, and 2.4–5V operation. Ideal for voice, audio recording, and FFT projects.

 

The MAX4466 Electret Microphone Amplifier Breakout Board gives your microcontroller project a reliable audio input channel. Built around the MAX4466 amplifier IC, this fully assembled and tested module ships with a wideband electret microphone already soldered on, so you can start capturing sound with just three wire connections. Its wide supply voltage range (2.4 V – 5 V DC) makes it a natural fit for both 5 V Arduino boards and 3.3 V platforms such as ESP32 and Raspberry Pi.

Key Features

  • Onboard Electret Microphone (20 Hz – 20 kHz): Full audible-spectrum coverage → suitable for voice, music, and environmental sound capture.
  • Adjustable Gain Trimmer: Small potentiometer on the back of the board → fine-tune sensitivity without extra components.
  • Wide Supply Voltage (2.4 V – 5 V DC): Single supply range → compatible with 3.3 V and 5 V microcontroller platforms.
  • Fully Assembled & Tested: Ready to use out of the box → no soldering of the mic or IC required.
  • Analog Output: Direct connection to any ADC pin → easy integration with Arduino analogRead() or ESP32 ADC.

Pinout & Wiring

PINSymbolDescription
1GNDConnect to system ground
2VCCSupply voltage 2.4 V – 5 V DC
3OUTAnalog audio output → connect to ADC input

Wiring note: Connect GND → GND, VCC → 3.3 V or 5 V, OUT → any analog input pin. The output is an analog signal and is not designed to drive speakers or headphones directly — an external audio amplifier is required for speaker output.

Compatibility

  • Arduino UNO / Nano (5 V): Connect VCC to 5 V and OUT to any A0–A5 analog pin.
  • ESP32 / ESP8266 (3.3 V): Connect VCC to 3.3 V and OUT to any ADC-capable GPIO.
  • Raspberry Pi (3.3 V): Connect VCC to 3.3 V; use an external ADC (e.g. MCP3008) since Raspberry Pi has no native analog input.

Typical Applications

  • Voice changers & audio effects: Capture voice input and process it digitally in real time.
  • Audio recording & sampling: Record audio snippets to SD card or memory buffer via microcontroller ADC.
  • FFT & audio-reactive projects: Feed the analog output into an FFT library to drive LED visualisers or sound-level meters.
  • Clap / sound detection: Detect threshold events for automation triggers and smart home projects.
  • Noise & environment monitoring: Log ambient sound levels over time for IoT sensor nodes.

FAQ

Q: Can I connect the OUT pin directly to a speaker?
A: No. The OUT pin carries an analog audio signal intended for an ADC input, not a speaker load. You will need a dedicated audio amplifier module between this board and any speaker or headphone.

Q: How do I increase or decrease the microphone sensitivity?
A: Use a small screwdriver to adjust the trimmer potentiometer on the back of the board. Turning it increases or decreases the amplifier gain, allowing you to tune sensitivity for your environment.
