LM386 Audio Amplifier Module 4-12V

The LM386 Audio Amplifier Module is a small, low-power audio amplifier board based on the LM386 chip. It runs from 4 V to 12 V and boosts weak audio signals from an Arduino, MP3 player, phone or microphone preamp enough to drive a small speaker. It is a simple, low-cost way to add sound to battery-powered gadgets and DIY electronics projects.

LM386 Audio Amplifier Module Specifications

• Amplifier IC: LM386 low-voltage audio power amplifier
• Supply voltage: 4–12 V DC
• Channels: 1 (mono)

LM386 Audio Amplifier Module Applications

• Adding sound, tones and voice to Arduino and ESP32 projects
• Small speakers for MP3, radio and phone audio
• Intercoms, doorbells and alarm sounders
• Learning audio amplification in electronics classes

What's in the Box

• 1 × LM386 audio amplifier module

Tip: Feed the module a line-level or other small signal, not the output of another amplifier, and keep the input and speaker wires short to avoid hum. A separate supply or a large capacitor across the power pins helps reduce noise from motors or Wi-Fi boards.
