Questions

What parts does the Draw use?

32 parts, built around the TPD4E002DRL. 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 Draw KiCad files?

From the notthetup/draw repository on GitHub, at the commit this page was made from: the board is schematics/draw.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Draw design in my own project?

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