Perfect for Arduino Clap Switch

Works great with my Uno board. Sensitivity is easy to adjust using the small screw on the board. Highly recommend for beginners.

Okay for beginners

Works but documentation was sparse. Had to look up wiring diagrams online to get it working with my ESP32.

Good value

Solid module but took some time to calibrate the potentiometer correctly. Once set up, it responds well to claps.
