Questions
What parts does the Zerow bit3 use?
74 parts, built around the CP2104EK, BIT3 and RJ45. 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 Zerow bit3 KiCad files?
From the lazywalker/ostar-pcb repository on GitHub, at the commit this page was made from: the board is ostar-pcb-widora_bit3.0/zerow bit3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Zerow bit3 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
