style="color:#000000;font-size:14px;">在训练营官方原理图的基础上，增加了一个RGB彩灯，用于充电状态显示，增加了晶振电路以及部分引出口，方便后续调试与再开发(详情见原理图附件)。</span></li> <li><span style="color:#000000;font-size:14px;">由于dcdc电源电路在5V输入时未能稳定输出3.3V，个人能力不足以对参数进行修正，因此使用AMS1117线性稳压电路代替官方的BL9342电源电路。</span></li> <li><span style="color:#000000;font-size:14px;">下载口和串口等调试接口改为贴片焊盘，进一步节省PCB空间。</span></li> </ol><p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt
