Questions
How big is the Charon 32U4 Hotswap PCB?
It measures 304.8 × 97.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Charon 32U4 Hotswap use?
148 parts, built around the ATMEGA32U4-AU, USBLC6-2P6 and BAV70. 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 Charon 32U4 Hotswap KiCad files?
From the PiKeeb/charon-keyboard repository on GitHub, at the commit this page was made from: the board is pcb/Charon_32U4_Hotswap/Charon_32U4_Hotswap.kicad_pcb and its schematic pcb/Charon_32U4_Hotswap/Charon_32U4_Hotswap.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Charon 32U4 Hotswap design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
