Questions
How big is the LegoLight R2 PCB?
It measures 30 × 65 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LegoLight R2 use?
82 parts, built around the ATSAMD21E18A-AF, PCA9685PW, PCA9306D and SK6812. 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 LegoLight R2 KiCad files?
From the averrin/LegoLight repository on GitHub, at the commit this page was made from: the board is Hardware/LegoLight_R2/LegoLight_R2/LegoLight_R2.kicad_pcb and its schematic Hardware/LegoLight/LegoLight.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LegoLight R2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask averrin before reusing the design.
