Pointless having no info
This forum is mainly for discussing Kicad. Things wander a bit sometimes but this is not the proper forum to gauge interest in a project. Since I don’t see full project files at the link given all links will be removed.
I did leave the info in case someone wanted to look into it. But you come on with a first post and say nothing about Kicad but mention you are trying to gauge interest in a board you want to sell? Where is the Kicad tie? Just using Kicad to design the board isn’t enough. I’m not trying to be difficult here but the forum is about using the software and not the projects made with it.
