Good value
Works well for the price. The soldering pads are a bit small for beginners, but functionally it is solid.

Great for Arduino projects
Works perfectly with my Arduino Uno. The audio output is clear and the gain settings are easy to configure by bridging the pads.

Low noise performance
The noise floor is very low compared to other modules I tried. Excellent for voice recognition projects.

Perfect for voice detection
Used this for a voice activation project in university. Sensitivity is adjustable and it picks up speech clearly.
Q: How do I change the gain?
A: There are pads on the board to select between 24dB, 29dB, 34dB, or 39dB by soldering a bridge.
Q: Does this come with a microphone?
A: Yes, an electret microphone is included on the board.
Q: Can I use this with 3.3V logic?
A: Yes, the operating voltage range supports 3.3V systems comfortably.
Q: Is the output digital or analog?
A: This module provides an analog audio output signal suitable for ADC input.
Q: What is the maximum distance for voice capture?
A: Depending on the environment, it typically captures clear voice within 1 to 3 meters.
