Questions
How big is the KiCAD Board PCB?
It measures 57.7 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KiCAD Board use?
47 parts, built around the ESP32-WROOM-32, ROF-78E3.3-0.5SMD-R, LTR-303ALS-01 and SI7020-A20-GM. 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 KiCAD Board KiCad files?
From the XasWorks/dragon-home repository on GitHub, at the commit this page was made from: the board is Hardware/dragon-cookie/KiCAD_Board/KiCAD_Board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the KiCAD Board 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).
