Audio Amplifier Board kit

12V Best Mini Audio 功放板，用于双向音频语音通信无线视频音频链路

功能:

The main function of the audio power amplifier board is to amplify the output and input voice signals with the wireless IP ethernet transmission and volume adjustment function

This is an Audio power amplifier board. Our wireless video and audio data link TX900, has an Audio interface, which can realize two-way voice intercom, but its voice is very small and needs to be amplified by a voice power amplifier board. , the received voice is amplified through the amplifying board to enhance the sound, which can be passed to the microphone and speaker of the intercom headset.
