用AI画电路板AI EDA初探Creating WiFi Radio with CELUS: A Step-by-Step Tutorial 使用CELU.IO创建WiFi收音机：分步教程结论：整体还不太成熟，所选器件单元是欧美思维，器件选型成本和咱们华强北还是无法比。可以关注迭代，看客就当走马观花就行了；不过里面的单元模块还带有AI提问的这个比较好，值得国内EDA从业者学习。话不多说上正文：本教程目的是让我们深入了解如何使用CELUS设计平台构建WiFi收音机实战项目。本指南的重点是使用该平台来选择正确的解决方案，并整合一个项目，让您可以将音乐和节目从互联网直接传输到您自己构建的扬声器。阅读详情
