Questions
What parts does the Demonstrate use?
7 parts, built around the ESP32-C3-WROOM-02-H4 and ARDUINO UNO R3. 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 Demonstrate KiCad files?
From the AngeloDuenas/Demonstration repository on GitHub, at the commit this page was made from: the board is demonstrate.kicad_pcb and its schematic demonstrate.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Demonstrate design in my own project?
Its repository states no licence, so its author keeps all rights: ask AngeloDuenas before reusing the design.
