Questions
How big is the Jekyll one PCB?
It measures 76.2 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Jekyll one use?
24 parts, built around the ESP32-C3-MINI-1 and AMS1117-3.3. 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 Jekyll one KiCad files?
From the firefly/prototyping repository on GitHub, at the commit this page was made from: the board is mixing-board-jekyll/jekyll-one/jekyll-one.kicad_pcb and its schematic mixing-board-jekyll/jekyll-one/jekyll-one.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Jekyll one design in my own project?
Its repository states no licence, so its author keeps all rights: ask firefly before reusing the design.
