<h1 style="line-height: 1.8;">2、硬件部分</h1>
<h2 style="line-height: 1.8;"><span style="color: #2dc26b;">1. 主控选择STM32G070CBT6，本来使用STM32G030C8T6，但由于使用Freertos和储存LCD图片，Flash和SDRAM不足，所以换成了STM32G070CBT6。</span></h2>
<p style="line-height: 1.8;"><img src="//image.lceda.cn/pullimage/0CV7pYPLGq2jNeaQebhWSoHJXMti0i2rpU9pkMjt.png" alt="" width="618" height="658" /></p>
<h2 style="line-height: 1.8;"><span style="color: #2dc26b;">2. 电源输入部分：带充电保护，防止电池过充和过放，并且自动控制充电电流，更好的保护电池。type-c母座。</span></h2>
<h3 style="line-height: 1.2;"><span style="color: #2dc26b;">最大充电电流：1000mA</span></h3>
<h3 style="line-height: 1.2;"><span style="color: #2dc26b;">充电截止电压：4.2V</span></h3>
<h3 style="line-height: 1.2;"><span style="color: #2dc26b;">电池过放保护电压：2.4V</span></h3>
<h3 style="line-height: 1.2;"><span style="color: #2dc26b;">最大输出电流：2A （建议1A内使用）</span></h3>
<h3 style="line-height: 1.2;"><span style="color: #2dc26b;">输出电压：4~12V (可改成更高输出)</span></h3>
<h2 style="line-height: 1.2;"><span style="color: #2dc26b;">type-c接电源输入端，蓝灯亮起、红灯快速闪烁，表明有电源接入。</span><span style="color: #2dc26b;">电池充电，红灯常亮。</span><span style="color: #2dc26b;">充满电后蓝灯亮起。</span></h2>
<h2 style="line-height: 1.2;"><span style="color: #2dc26b;">当输充电输入端接入电源时，从电源输入端获得电流，如果没有接电源，从电池获得电流，电池电压低于2.4V时，自动关闭输出。</span></h2>
<h2><span style="color: #e03e2d; background-color: #fbeeb8;">注意事项：</span></h2>
<h2><span style="color: #e03e2d; background-color: #fbeeb8;">第一次接入电池时，可能无电压输出，需要在电源输入端上电激活保护电路。当使用手机充电器供电时，必须要能输出1A以上，否则可能会不能正常充电。</span></h2>
<h2><span style="color: #e03e2d; background-color: #fbeeb8;">该电路升压后输出电压可调，焊接时最好先焊接电源部分，并将升压后的输出电压调节至5V，再焊接其他电路（焊接好其他电路先调输出电压为5V，最后才焊AMS1117 3.3V）。</span></h2>
<h2><span style="color: #e03e2d; background-color: #fbeeb8;">注意区分电池正负极。</span></h2>
