Questions
How big is the Overboard PCB?
It measures 285 × 95.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Overboard use?
189 parts, built around the SK6812MINI-E and AST1109MLTRQ. 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 Overboard KiCad files?
From the t33chong/overboard repository on GitHub, at the commit this page was made from: the board is overboard.kicad_pcb and its schematic overboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Overboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask t33chong before reusing the design.
