Questions
How big is the MiniBee PCB?
It measures 23.3 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MiniBee use?
40 parts, built around the STM32WB5MMG, SY8201ABC 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 MiniBee KiCad files?
From the Jana-Marie/MiniBee repository on GitHub, at the commit this page was made from: the board is MiniBee.kicad_pcb and its schematic MiniBee.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MiniBee design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jana-Marie before reusing the design.
