About this item.
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.Handy! Great small low frequency audio power amplifier to be used for driving small speakers or to build an RC sound module with an arduino. It could be hooked up to headphones directly too 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.It works with RC truck sound system or an RC boat project It is so simple, so cheap, but works perfectly. Just plug power, connect input, and loudspeakers and you have good thing for listening whatsoevery you want to listen Fantastic pre-assembled assembled Amp provides a gain of 200. This neat amplifier module works really well for your audio experiments and prototypes. Very little distortion.

If you need a bit of power for you small speakers, this well made micro audio amp amplifier module will do. Just using the right source and output devices, it is a wonderful miniature version of an old circuit. 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. DIY LM386 super audio amplifier 200X gain audio amp LM386 mono amplificador module board 5-12V. Features: 1. On-board LM386 Chip 2. Signal Gain 200 (multiplier) 3. On-board speaker wiring block/holder 4. On-board 10K variable resistor, you can adjust the amplification volume. 5. Onboard volume control potentiometer clockwise to increase the volume. 6. On-board LED for power indicator 7. The chip pin leads, can be directly input audio signal 8. Operating voltage: 5-12V DC 9. Board size: 41 x13mm(1.6*0.6inch) 10.Low distortion,the adjustable pot for distortion is very nice to have 11.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.(refer to http://www.mpja.com/download/31805misch.pdf ) 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: 5 X LM386 audio amplifier module
