Questions
How big is the Bbcs macrofidget PCB?
It measures 57.2 × 43.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bbcs macrofidget use?
11 parts, built around the SK6812MINI-E. 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 Bbcs macrofidget KiCad files?
From the frosetrain/bbcs-macrofidget repository on GitHub, at the commit this page was made from: the board is pcb/bbcs-macrofidget.kicad_pcb and its schematic pcb/bbcs-macrofidget.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bbcs macrofidget design in my own project?
Its repository states no licence, so its author keeps all rights: ask frosetrain before reusing the design.
