一、原理图的基本构成要素：      元器件，即原理图符号；      电气连接；      必要的注释；二、绘制原理图的基本原则       原理图设计的基本原则是整齐美观，能清晰准确的反映设计者意图，方便交流。三、原理图设计的基本流程       1.新建原理图       2.设置图纸参数       3.载入原理图库       4.

HX711是一款专为高精度电子秤而设计的24位A/D转换器芯片。与同类型其它芯片相比，该芯片集成了包括稳压电源、片内时钟振荡器等其它同类型芯片所需要的外围电路，具有集成度高、响应速度快、抗干扰性强等优点。降低了电子秤的整机成本，提高了整机的性能和可靠性。该芯片与后端MCU 芯片的接口和编程非常简单，所有控制信号由管脚驱动，无需对芯片内部的寄存器编程。输入选择开关可任意选取通道A 或通道B，与其

PCB（PrintedCircuitBoard），中文名称为印制电路板，又称印刷电路板、印刷线路板，是重要的电子部件，是电子元器件的支撑体，是电子元器件电气连接的提供者。由于它是采用电子印刷术制作的，故被称为“印刷”电路板。Solder层为露铜层，即铺绿油的层，也叫阻焊层；Paste层为钢网层，工厂加工贴片的时候需要，也叫助焊层；Keep-Out Layer 层为分割层，用来给
