The BMT LM386 AUDIO AMP MODULE is a compact, low-power audio amplifier board designed around the popular LM386 audio amplifier IC, making it an excellent solution for hobbyists, students, makers, and electronics enthusiasts. Operating from a 4V to 12V DC power supply, this module delivers clear audio amplification while consuming very little power, making it especially suitable for portable and battery-powered applications.
Designed with simplicity in mind, the module requires very few external components, allowing quick integration into DIY audio circuits, portable speakers, radios, intercoms, educational projects, and small sound systems. The onboard volume control potentiometer allows convenient adjustment of the output level, while the default amplifier gain of 200 provides strong audio amplification for low-level input signals.
An onboard power indicator LED provides visual confirmation that the module is powered correctly, making troubleshooting and operation easier. Thanks to its compact 41 × 13 mm PCB, the module fits easily into space-constrained electronic projects while delivering reliable performance with low distortion.
The LM386 is widely recognised for its dependable operation and ease of use, making this module an excellent choice for beginners learning audio electronics as well as experienced designers building custom amplification circuits. Whether you're repairing vintage audio equipment, building a portable amplifier, or experimenting with sound projects, the BMT LM386 Audio Amplifier Module offers an affordable and effective solution.
