Questions
How big is the Sunbie PCB?
It measures 1.3 × 49 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sunbie use?
24 parts, built around the BME280, TSL25911FN, LSM6DS3 and WS2812B. 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 Sunbie KiCad files?
From the avycado13/sunbie repository on GitHub, at the commit this page was made from: the board is sunbie.kicad_pcb and its schematic sunbie.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sunbie design in my own project?
Its repository states no licence, so its author keeps all rights: ask avycado13 before reusing the design.
