Questions
How big is the Cloud dripper PCB?
It measures 50.8 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cloud dripper use?
75 parts, built around the ESP32-C3-MINI-1, R-78E5.0-1.0, AMS1117-3.3 and AO3400A. 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 Cloud dripper KiCad files?
From the AlessioMorale/cloud_dripper repository on GitHub, at the commit this page was made from: the board is cloud_dripper.kicad_pcb and its schematic cloud_dripper.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cloud dripper design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
