1This 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 a filter circuit to ensure that the power supply ripple is small, and the larger ripple makes more powerful noise. 2Such board is equipped with a precision high-quality op amp core, which can adjust the amplification gain, and the noise is very small, also the sound is clear and bright! 3Output of the board can be directly connected to the audio input of the audio, or the audio input of the computer to realize voice chat or voice amplification. 4The board will amplify the audio signal input from the audio input port or directly amplify the pickup signal of the onboard microphone. 5Capacitive microphone (column microphone pickup) audio signal amplification can be realized.
