On-board LM386 Chip Signal Gain 200 (multiplier) On-board speaker wiring block/holder On-board 10K variable resistor, you can adjust the amplification volume. Onboard volume control potentiometer clockwise to increase the volume. On-board LED for power indicator The chip pin leads, can be directly input audio signal Operating voltage: 5-12V DC Low distortion,the adjustable pot for distortion is very nice to have Screw terminal for speaker output connection
How to Use: It's printed right on the board. VCC in and GND for power, the other pins are for audio + and -. then the speaker screws into the green terminal.
Note: This amplifier works fine even with weak input like a microphone input. Because of its sensitivity, care should be taken to have good shielding or the amplifier will also capture noise. If you have a stereo application, then you will need to use two modules, however a single module is useful if you were experimenting with transistor radios.
Package included: 10 x LM386 audio amplifier module
