FLOSS for custom circuits

Hi there all,

I’d like to build a custom PSU for one of my C64s. I’d like to use FLOSS software in drawing, as well as simulating current input, treatment, and output.
Is there a comprehensive FLOSS application that I could use?

Thanks and have a nice Sunday

Inside KiCad there is a nice circuit simulator...

Thanks all,

will give KiCad a try :slight_smile:


I confirm,
I’m using it a lot for school, it’s great!
