Questions
How big is the Robocat PCB?
It measures 90 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Robocat use?
87 parts, built around the LM324. 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 Robocat KiCad files?
From the Windfisch/robocat repository on GitHub, at the commit this page was made from: the board is pcb/pcb/pcb.kicad_pcb and its schematic pcb/pcb/pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Robocat design in my own project?
Its repository states no licence, so its author keeps all rights: ask Windfisch before reusing the design.
