Good quality, slight noise
Solid build quality. I noticed some background hiss when gain is maxed out, but overall great value for the price.

Easy to Integrate
Plug and play with standard headers. Documentation was clear enough to get started quickly on my prototype.

Great for ESP32 Projects
Used this for a smart home voice trigger. Low power consumption and reliable output when paired with an ESP32.

Sensitivity varies
Had to tweak the wiring to reduce interference. Works okay but requires careful shielding in noisy environments.

Perfect for Voice Recognition
Works flawlessly with my Arduino Nano. The AGC feature really helps stabilize the input levels for my speech project.
Q: Is there a digital output for clap detection?
A: No, this is an analog amplifier module. You need to process the signal in code to detect claps.
Q: Can I adjust the gain manually?
A: The MAX9814 has automatic gain control. Fixed gain versions exist, but this one adjusts automatically.
Q: How do I connect this to an Arduino Uno?
A: Connect VCC to 5V, GND to GND, and OUT to an analog pin like A0. Ensure common ground.
Q: Does this output digital or analog signal?
A: This module outputs an analog audio signal compatible with ADC pins on microcontrollers.
Q: Can I power this with 3.3V?
A: Yes, the operating voltage range is 2.7V to 5.5V, so 3.3V is safe and supported.
