Questions
What parts does the Quad unibody placement0 use?
64 parts, built around the ESP32-C3-MINI-1-H4X, LTC3534EGN#PBF, RQ5E040AJTCL and ICM-42670-P. 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 Quad unibody placement0 KiCad files?
From the ajwock/quadcopter repository on GitHub, at the commit this page was made from: the board is cad/quad_unibody/quad_unibody_placement0.kicad_pcb and its schematic cad/home_copter/home_copter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quad unibody placement0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ajwock before reusing the design.
