Review on π Battery Power Supply Audio Mono Amplifier Module Board NJM386D LM386 by Jessica Torma
Excellent project amplifier
This is my second project with one of these audio amplifiers. I developed it as a DSP filter for my amateur radio. The build quality is top notch and the choice of x20 or x200 amp gain is a real plus. The audio output is crisp and clear. These amps are better than I could ever build, especially at this price point. I hope Revain will continue to offer these amps.
