LM386 audio amplifier module mini power amplifier board, DC 3-12V, with adjustable volume control.
Power supply: DC 3-12V, recommended >= 5V;
Speaker power: 0.5W -10W, an 8W speaker is recommended for optimal performance. On-board volume control potentiometer (turn clockwise to increase volume), featuring a power indicator light. Low power consumption, adjustable gain, broad supply voltage range, minimal external components needed. Widely used in tape recorders and radios. Low static power consumption, quiescent current approximately 2mA, well-suited for battery-powered applications
