Create Circuit Diagram

How can i create fritzing circuit diagram like this

How to download the software or is it online based?

Hi @Rahulk15 ,
fritzing was a free and open-source software. They recently started charging a fee for downloading the software, but the source code is still available for free. If you want it for free you will have to build it from the source code. That would be operating system specific.

Download: Fritzing

Check out this article to build it from source code.

Is there any alternative to fritzing where I can add Bolt IoT module as a component.
