Questions
How big is the Orca hana PCB?
It measures 71.1 × 35.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Orca hana use?
41 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 Orca hana KiCad files?
From the funcoolgarage/orca-hana repository on GitHub, at the commit this page was made from: the board is orca-hana.kicad_pcb and its schematic IO_Connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Orca hana design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
