Questions
How big is the Halictus PCB?
It measures 327.4 × 135.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Halictus use?
174 parts, built around the SK6812 and BSS138. 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 Halictus KiCad files?
From the tr3foil/halictus repository on GitHub, at the commit this page was made from: the board is halictus.kicad_pcb and its schematic halictus.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Halictus design in my own project?
Its repository states no licence, so its author keeps all rights: ask tr3foil before reusing the design.
