Creating a schematic from scratch for a photon project

Hi, I have a feeling this is a trivial question since everyone that posts a projects into the particle project repository seems to know how to do it. I haven’t been able to find the right tool to create these nice schematics that all projects seem to have.Is it a generic tool or a particle specific application that is being used to create these JPEG schematics?


Do you mean Fritzing schematics?

Another frequently used tool is Eagle


Yes. Exactly wehat I am looking for. Thanks.
