Questions
How big is the Alpakka PCB?
It measures 130 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Alpakka use?
78 parts. 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 Alpakka KiCad files?
From the stormbots/MarketingBot repository on GitHub, at the commit this page was made from: the board is ControllerPCB/projects/alpakka/alpakka.kicad_pcb and its schematic Control Box Interface Board/board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Alpakka design in my own project?
Its repository states no licence, so its author keeps all rights: ask stormbots before reusing the design.
