Questions
How big is the Badge PCB?
It measures 100 × 61 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Badge use?
27 parts, built around the ESP32-S3-WROOM-1-N8, AMS1117 and WS2812B. 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 Badge KiCad files?
From the AnakinDmaker/badge_pcb repository on GitHub, at the commit this page was made from: the board is badge.kicad_pcb and its schematic badge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Badge 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).
