The LM386 Audio Amplifier Module is a compact, low-voltage amplifier board designed for audio applications. Based on the popular LM386 IC, this module is perfect for boosting weak audio signals from devices like microphones, MP3 players, or mobile phones to drive small speakers (typically 0.5W to 1W output).

Ideal for DIY electronics and educational projects, the module operates on a wide voltage range (4V–12V) and offers built-in gain control, making it easy to adjust volume and performance. It’s widely used in small sound systems, intercoms, radios, and audio experiments with microcontrollers like Arduino.
