Questions

What parts does the Coffee Roaster Project use?

19 parts, built around the MAX31856, MOC3011M and DFP10112. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Coffee Roaster Project KiCad files?

From the eddietheengineer/autocoffeeroaster repository on GitHub, at the commit this page was made from: the board is Coffee Roaster Project/Coffee Roaster Project.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Coffee Roaster Project design in my own project?

Its repository states no licence, so its author keeps all rights: ask eddietheengineer before reusing the design.
