This LM386 single-channel amplifier board is a popular beginner-level mono audio amplification module widely used for electronic DIY assembly kits. It features adjustable gain control that can reach a maximum magnification of 200 times, which greatly amplifies weak audio signals for small speakers.
It supports low-voltage DC power supply from 5V to 12V, allowing power supply via lithium batteries, USB power modules or small switching adapters. Optimized peripheral circuits effectively reduce background hum and distortion, delivering smooth, clear sound playback for low-power speaker units.
All wiring pads are clearly labeled for power input, audio signal input and speaker output, without complicated circuit debugging requirements. The mini PCB structure saves installation space and is easy to embed inside homemade audio devices.
Ideal for electronic teaching experiments, mini desktop speakers, portable audio players, radio signal amplification and student DIY electronic kits. Simply connect a matched power source, audio source and small speaker to complete a simple mono audio amplification system.
