Questions
How big is the Roulette PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Roulette use?
64 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 Roulette KiCad files?
From the sangyoungn/led-roulette-with-circuitpython repository on GitHub, at the commit this page was made from: the board is hardware/roulette/roulette.kicad_pcb and its schematic hardware/roulette/LEDs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Roulette design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
