Questions
What parts does the Breakbox use?
8 parts, built around the ESP32-S3-WROOM-1-N8R8, PAM8403DR, AMS1117-3.3 and TP4056. 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 Breakbox KiCad files?
From the gl1tchxd-git/breakbox-hardware repository on GitHub, at the commit this page was made from: the board is KiCad/breakbox.kicad_pcb and its schematic KiCad/breakbox.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Breakbox design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
