Questions
How big is the Cablebot controller PCB?
It measures 95.1 × 38.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cablebot controller use?
15 parts, built around the WS2812B. 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 Cablebot controller KiCad files?
From the romi/romi-cablebot repository on GitHub, at the commit this page was made from: the board is Hardware/Electronics/cablebot_controller/cablebot_controller.kicad_pcb and its schematic Hardware/Electronics/cablebot_controller/cablebot_controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cablebot controller 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).
