Questions
How big is the ChillyBoard PCB?
It measures 36 × 68.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ChillyBoard use?
75 parts, built around the ESP32-S3, W25Q128JVSIQ, AMS1117-3.3 and AO3401A. 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 ChillyBoard KiCad files?
From the Stanlee1234/ChillyBoard repository on GitHub, at the commit this page was made from: the board is chilly_board.kicad_pcb and its schematic chilly_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ChillyBoard 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).
