Questions
How big is the FlyingChecklist KiCad PCB?
It measures 48.5 × 74.8 mm and has 4 copper layers, 1 mm thick.
What parts does the FlyingChecklist KiCad use?
88 parts, built around the ESP32-S3-WROOM-1-N8, AP3602AKTR-G1, XC6220B331MR and DMP2045U. 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 FlyingChecklist KiCad KiCad files?
From the SarahAlroe/FlyingChecklist-Hardware repository on GitHub, at the commit this page was made from: the board is FlyingChecklist-KiCad/FlyingChecklist-KiCad.kicad_pcb and its schematic FlyingChecklist-KiCad/FlyingChecklist-KiCad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FlyingChecklist KiCad design in my own project?
Its repository states no licence, so its author keeps all rights: ask SarahAlroe before reusing the design.
