<strong>📖原理图说明:</strong> <br></div>
<p>程序烧录部分:
内置串口芯片CH343P,可以直接接入5V,无需而外的接入降压芯片,在充电电源没接入时芯片不工作,CH343P的RTS引脚接入到负载开关的使能引脚在需要烧录程序时RTS会有电平变化,从而重启主控芯片,省去手动重启去烧录程序。<img src="https://image.lceda.cn/oshwhub/pullImage/1595a49c3f7948e0b085f901b35e2d78.jpg" alt="程序下载电路.jpg">传感器部分:
让设备功能更加丰富,集成了温湿度传感器SHT30和环境光传感器BH1750。

充电芯片采用IP5306,默认没有使用它的升压功能,这个芯片还有个小坑,就算不使用升压的输出引脚关闭了它引脚会有脉冲检测,平均2点多的电压,这个过程也是耗电的虽然很少。<img src="https://image.lceda.cn/oshwhub/pullImage/7ecb66874d884f2dad6ce43a93ee0a67.jpg" alt="充电电路.jpg">音频部分:

<strong>🎁踩坑小日记:</strong> <br>
1. 底板跟主板的链接用了5条线,所有就找了个5PIN的接口,等画好板打板,买材料的时候fpc找不到5PIN的最后买了6PIN的回来减掉1PIN。<br>
2.画PCB的时候没注意FPC接口的主板跟底板的引脚对调了,所以只能反着接不能同向接。<br>
3.最开始做的充电检测引脚是PA35,好像不能浮空输入,一直都配不了,分压后的电压会被它拉下去,最后改成PA44解决。<br>
