10Pcs Audio Amplifier Module Mini LM386 Mono Power AMP Module 200 Times Gain Amplifier Board Mono Power Amplifier HiFi DIY

Description

• Onboard LM386 chip, with 20 multiplier benefits circuit design, on-board speaker wire holder, on-board 10K variable resistor, you can adjust the amplification volume.
• LM386 audio amplifier board power indicator,the main feet of the chip has been leaded, can input audio signal directly, wide operating voltage range: 4-12V
• LM386 audio power amplifier to be used for driving small speakers or to build an RC sound module.
• This audio amplifier module is a mono audio amplifier based on the LM386 chip,which is useful for DIY many HAM radio experiments.It is a very cost effective method of small signal amplification.Very convenient instead of using separate components.
• This tiny Op Amp module is good and delivers clear crisp sound.Easy to adjust volume with variable resistor.A convenient screw terminal allows the user to connect a suitable loudspeaker without any soldering.

Simply connect a 4-8 Ohm speaker and amplify your sound.
It can used with FM receiver kit or WTV020SD-16P music module, door bell, RC sound system.
You can definitely use this module for other musical projects too.

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
