Questions
How big is the Beeball PCB?
It measures 91.4 × 58.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Beeball use?
16 parts, built around the PMW3360DM-T2QU. 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 Beeball KiCad files?
From the LilyRose2798/beeball repository on GitHub, at the commit this page was made from: the board is beeball.kicad_pcb and its schematic beeball.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Beeball 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).
