<p>注：*为必填项。</p> <p>【请在报名阶段填写 ↓】 <em>  1、自我/团队介绍 个人项目，主要是用来熟悉 pcb 绘图，全程使用的是立创EDA，除了个别几个 bug 外，还是比较方便的。 </em>  2、简要介绍项目 一个功耗测试的项目，本身有这方便需求，需要找一款稳定，精度高便于携带使用，且比较现代化可以远传，长久数据测量保存，可以数据可视化话的一款功耗测量产品。</p> <p>但因为这个项目启动较晚，最近一两周刚开始做，加上个人硬件基础薄弱，这个 v1.x 版本成本过高，选用的芯片也是世面已有方案，但精度和最小量程还不够满足需求，后续会学习研究，重构这个项目。</p> <p>这个项目目前只要用来学习使用立创 EDA，和 PCB 制版。</p> <p>【请在竞赛阶段填写 ↓】 *  1、描述项目详情 使用 INA226 芯片，持续采集负载外设的功耗，每秒约 100 次数据做平均，定时器一秒钟刷新一次数据，用来在 oled 上面显示和串口传输数据。</p> <p>*  2、描述项目所面临的挑战及所解决的问题 基本能够满足简单的测量，目前精度和万用表比较接近，本项目唯一的有点，是在上位机上存储了数据，可以长时间测量累计功耗，由于时间太急，没能把数据可视化等功能做出来。</p> <p>*  3、描述项目硬件、软件部分涉及到的关键点 硬件采用 INA226 这款世面早已使用的成熟芯片，稍微缩小了整个硬件的尺寸，绝大多数封装采用的 0402 封装，但仍然有进一步提高的空间，应该可以减少到 1.5 寸的大小以内，在 oled 的尺寸左右，这样可以便于方便携带。</p> <p>*  4、项目材料清单展示</p> <table> <tr> <th></th> <th></th> <th></th> <th></th> <th></th> <th></th>
