免费在线原理图查看器 — 在浏览器中查看电路图

Free schematic viewer online — circuit diagram rendered in MakerSuite 3D

无需安装任何软件即可查看原理图

阅读电路原理图通常需要启动KiCad、Altium或Eagle等大型EDA工具。MakerSuite 3D现在包含基于浏览器的原理图查看器,让您即时打开.kicad_sch文件,无需安装、注册或文件上传。只需拖放即可阅读电路图。

什么是原理图查看器?

原理图查看器显示电路设计中电子元件之间的逻辑连接。与显示物理板布局的PCB查看器不同,原理图查看器展示电气关系——哪个引脚连接到哪个网络、电源如何在电路中流动、元件如何组织成功能模块。MakerSuite 3D在HTML5 Canvas上以流畅的平移和缩放渲染原理图,即使是复杂的多页设计也能轻松浏览。

原理图查看器主要功能

支持的原理图格式

原理图查看器目前支持KiCad 6、7和8的KiCad原理图文件(.kicad_sch)。这些文件使用S表达式格式,查看器完全在浏览器中解析。未来版本计划支持更多格式。

谁需要原理图查看器?

隐私与安全

与PCB查看器一样,原理图查看器在浏览器中本地处理所有内容。您的.kicad_sch文件永远不会上传到任何服务器。这使其可安全用于专有设计和机密项目。
