Questions
How big is the Pentoxide PCB?
It measures 283 × 58 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pentoxide use?
74 parts, built around the SK6812MINI-E. 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 Pentoxide KiCad files?
From the lycronisxd/pentoxide repository on GitHub, at the commit this page was made from: the board is pcb/kicad-files/pentoxide.kicad_pcb and its schematic pcb/kicad-files/pentoxide.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pentoxide design in my own project?
Its repository states no licence, so its author keeps all rights: ask lycronisxd before reusing the design.
