Questions
How big is the Rabbitboard PCB?
It measures 310.5 × 111 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rabbitboard use?
139 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 Rabbitboard KiCad files?
From the information-fiend/rabbitboard repository on GitHub, at the commit this page was made from: the board is PCB/pcb.kicad_pcb and its schematic PCB/pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rabbitboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask information-fiend before reusing the design.
