Publish heavy! Lichuang EDA professional version full offline client!

release time:2022-03-17Author source:SlkorBrowse:1330

I believe this moment, you and I have been waiting for too long. After several versions of public beta, the official version of professional client is finally released! Of course, it is still "free"!

Lichuang EDA will implement the free domestic PCB design tools to the end, and is determined to provide users with easy-to-use and efficient design tools!
Lichuang EDA Professional Client supports three operation modes.

  • "All-online mode" requires login. Both the library and the project exist in the cloud, which supports collaboration and automatic backup of the cloud project to the local area.

  • "Semi-offline mode" does not require login. Libraries and projects exist locally, so collaboration is not supported, and cloud system libraries are supported. This mode is recommended.

  • "Full offline mode" does not require login. Libraries and projects exist locally, so collaboration is not supported, and the use of cloud system libraries is not supported. Built-in 1w+ common system libraries.
