Questions
How big is the Rex60Hotswap PCB?
It measures 284.7 × 94.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Rex60Hotswap use?
180 parts. 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 Rex60Hotswap KiCad files?
From the LordsBoards/Rex60Hotswap repository on GitHub, at the commit this page was made from: the board is PCB.kicad_pcb and its schematic PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rex60Hotswap design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
