Features
1. This amplifier module can amplify the audio signal of a capacitive microphone (column microphone pickup). The board will amplify the audio signal input from the audio input port, or directly to the onboard microphone. The pickup signal is amplified, and the output of the board can be directly connected to the audio input end of the audio, or the audio input end of the computer, to realize voice chat or voice amplification, and the board has a high-quality operational amplifier core, and the amplification gain can be adjusted. The noise floor is small and the sound is clear and bright!
2. This board should be powered by battery (two or more dry batteries or a single lithium battery 18650). Secondly, it uses linear power supply. If you need to use switching power supply, please add filter circuit to ensure circuit power supply ripple. Small, the larger the ripple, the louder the noise will be.
3. Shipped for welding microphones. The 3P pins on the board are not soldered, but will be placed inside the package.
4. The board can directly realize the microphone signal acquisition and amplification, and can also enlarge the inserted external small microphone signal (this is a problem that many friends en counter the microphone volume is small)
Specification
1. Power:DC 2.6-10V
2. Input:the board is equipped with a capacitive microphone (sensitivity 58D)
3. Output:3.5 audio and 3P pin synchronous audio output port L and G (G is audio ground)
