# 国际电子工程联盟 (EE Union) - 工程师社区

> 国际电子工程联盟（eeunion.com）是面向电子工程师、学生与爱好者的独立、非商业中文技术论坛，讨论模拟与电源、数字与可编程逻辑（FPGA/CPLD）、MCU 与嵌入式、PCB 与工艺、EDA 工具、元器件选型、开源硬件项目以及求职与学习资源。
> EE Union (eeunion.com) is an independent, non-commercial Chinese-language forum for electronics engineers, students and hobbyists, covering analog & power circuits, digital logic and programmable logic (FPGA/CPLD), MCUs & embedded systems, PCB design & manufacturing, EDA tools, component selection, open-source hardware projects, and career/learning resources.

Primary language: zh-CN. Canonical host: https://www.eeunion.com/ . Posts are plain text written by members and by the site's editorial account 「国际电子工程联盟编辑部」.
