Questions

How big is the Boot camp pcb PCB?

It measures 101.6 × 101.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Boot camp pcb use?

35 parts, built around the DHT20. 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 Boot camp pcb KiCad files?

From the eshazen/reference_designs repository on GitHub, at the commit this page was made from: the board is boot_camp_pcb/boot_camp_pcb.kicad_pcb and its schematic boot_camp_pcb/boot_camp_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Boot camp pcb design in my own project?

Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
