Description: 为51单片机控制的音响功放板
一．带有3路外接音频信号输入：
1. 音频信号输入，可通过音频线输入CD、电脑、手机等音频信号。
2. 自带数字收音模块输入。
3. 通过3P针座预留外接输入。
4. 通过一个2P针座向外提供5V电压，一个2P针座提供单片机串口。
二．实现音频信号左右两路声道信号输出，可通过外接12V电压，1A以上适配器供电。或者通过8-10V交流电压供电。
三．由4位数码管显示，10个LED灯在无音频信号时为跑马灯模式；有音频信号时LED灯跟随信号强弱闪烁。-Audio power amplifier board controlled by 51 single chip microcomputer
One with 3- way external audio signal input:
1 audio signal input, can be input through the audio line CD, computer, mobile phone and other audio signals.
2 built-in digital radio module input.
The 3 seat reserved by 3P external input.
4 through a 2P hub to provide 5V voltage, a 2P hub provides serial.
Two. The implementation of audio signal about two channel signal output, 12V voltage through an external power adapter, 1A. Or through the 8-10V AC voltage power supply.
. by the four digital tube display, 10 LED lights in no audio signal for the marquee model audio signal LED lights follow signal intensity flicker.
