Solid choice for education
Bought ten of these for our student robotics club. They are durable enough for handling by students and provide consistent results for sound-following robots.

Good value but needs calibration
The sensor itself is great quality for the price. I had to spend some time adjusting the threshold in my code to get it to trigger reliably, but once set up, it works well.

Good for logic, not for Hi-Fi
Works exactly as described for triggering events based on sound. Do not expect studio-quality audio recording, but that is not what this module is designed for.

Perfect for voice activation projects
This module works flawlessly with my Arduino Uno. The signal is clean and the gain is just right for detecting claps or speech without too much background noise. Highly recommended for beginners.

Excellent preamp performance
The MAX4466 chip provides a very stable output. I used this for a sound level meter project and the linearity was impressive within the expected range.

Easy to use with provided code
I was worried about wiring this up, but the pins are clearly labeled. The sample code linked in the description got me started immediately. Great product!
Q: What is the power consumption of this module?
A: The typical supply current is approximately 0.9mA at 5V, making it suitable for battery-powered applications.
Q: Does this module output digital or analog signals?
A: This module outputs an analog signal representing the sound wave amplitude. You will need an ADC (like the one built into most Arduinos) to read it.
Q: Is the microphone sensitive enough to detect normal conversation from 2 meters away?
A: In a quiet environment, yes. However, for reliable detection at that distance, you may need to add an external amplifier stage or adjust your software thresholds.
Q: Can I connect this directly to a 3.3V microcontroller like ESP8266?
A: Yes, the MAX4466 operates comfortably between 2.7V and 5.5V, so it is fully compatible with 3.3V systems.
Q: Where can I find the source code mentioned in the title?
A: The link to the GitHub repository with sample code for Arduino and Python is included in the PDF manual inside the package and on our product support page.
