Questions
How big is the Sumobot PCB?
It measures 30.2 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sumobot use?
21 parts, built around the 74HC86D. 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 Sumobot KiCad files?
From the formesean/sumobot repository on GitHub, at the commit this page was made from: the board is schematic/v2/v2/v2.kicad_pcb and its schematic schematic/v1/sumobot/sumobot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sumobot design in my own project?
Its repository states no licence, so its author keeps all rights: ask formesean before reusing the design.
