Questions

How big is the Blade PCB?

It measures 87.5 × 38 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Blade use?

269 parts, built around the WS2812B-2020. 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 Blade KiCad files?

From the barn53/Lightsabers repository on GitHub, at the commit this page was made from: the board is kicad/Blade.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Blade 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).
