 原理图我用的是复用模块的方式进行设计，复用模块设计就类比与函数包装，用的时候只需要关注输入输出的引脚与其他模块的连接，不需要考虑内部的电气设计（比如电容，电阻），系统中的各个模块之间的关系，且像一些常用功能模块可以在其他工程中复用，有一定的迁移性（比如电源供电，USB, 按键），详情了解可看<a href="https://www.bilibili.com/video/BV1iC5TzTEm1/?spm_id_from=333.337.search-card.all.click&vd_source=dc203f6e0b4dcd755f7e93f502679607" target="_blank">立创天空星PCB教程视频</a></span></p> <p> </p> <p><span style="color:#95a5a6;font-size:14px">  布局的时候要注意实际的尺寸，多用立创EDA的3D 预览功能，如果你用的是插件的电解铝电容要注意大小不要高于TFT屏幕，TFT屏幕用的是插件的，加上插座的话，实际要高一些。</span></p> <p> </p> <p> </p> <p><span style="color:#95a5a6;font-size:14px">  可以导入DXF文件进行辅助设计，比如板框的尺寸，打孔的位置（常用的快捷键中心对齐，用的是京晓科技的设置，相关文件在附件），元器件的摆放位置。关于如何导入可以关注微信公众号京晓电路搜索相关文章。</span></p> <p><span style="color:#95a5a6;font-size:14px">  DXF文件在面板设计时，可以快速确定面板的相关尺寸，前提先设计好3D打印模型。</span></p> <p> </p> <p><span style="color:#95a5a6;font-size:14px">布线时要注意差分走线的处理，差分对，电源线（线宽）的回流路径，铺铜后检查死铜（禁止区域）和电流回流路径（放置缝合孔）</span></p> <p> </p> <ul> <li><em><strong><span style="--darkreader-inline-color:var(--darkreader-text-857f74, #827b6f);color:#857f74">焊接组装</span></strong></em></li> </ul> <p style="line-height:1.8">SF32LB52模组的焊盘比较小，焊接时注意使用的焊锡丝的流动性（含铅的比列or助焊剂）和尺寸（0.6mm），我用的时刀头的烙铁，我第一次焊时歪了，拆的时候心急没有等到合适的温度，焊盘脱落了，想飞线，结果这个模组的线又细又密。只好再买一个，第二次焊的时候连锡了，导致上电后屏幕不亮。</p> <p style="line-height:1.8"><em><strong>遇到的问题：</strong></em></p> <p style="line-height:1.8">上电后LED 灯不亮（引脚没有接反，两个引脚电压为3.3v左右），屏幕闪烁两次不亮，烧录程序进去时，LED亮，屏幕也亮，程序不能运行，能烧录进去。这个问题我在两块板子上都有，第二块板子发现主控焊接时连锡。</p> <p style="line-height:1.8">解决完后，能显示小智AI 的页面，但LED灯不亮（两个引脚电压3.3v左右，测的模组对应的两个焊盘电压3.3v左右），能连蓝牙共享网络，但到了对话时，屏幕熄屏只有背光有时黑屏。</p> <p style="line-height:1.8">问题可能出现在电源回流路径上，载流能力差，在PCB上要优化电源的线宽和铺铜的缝合孔。电池的供电不稳定，实测电池电压不够时，不能烧录，程序运行不稳定。我按官方的推荐购买的电池，我感觉很容易没电。这里可以优化一下供电设计，后续再搞了。</p> <p style="line-height:1.8">LED 灯的问题，软件代码的问题，在官方训练营微信群了解，只有在烧录的时候亮，烧录完成后不亮。（这个代码设计的还是有点反人性呀，可能是觉得小智AI工作的时候，一直亮着个灯不优雅吧，但在组装的时候我还以为焊错了呢。有能力的朋友可一改改）</p> <p style="line-height:1.8"><img
