Questions
How big is the SpringRobocon2026 mainboard PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SpringRobocon2026 mainboard use?
74 parts, built around the BA033CC0FP-E2, BA50BC0FP-E2, GS1010FL and MF-NSMF035X-2. 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 SpringRobocon2026 mainboard KiCad files?
From the KeioRoboticsAssociation/SpringRobocon2026_mainboard repository on GitHub, at the commit this page was made from: the board is SpringRobocon2026_mainboard.kicad_pcb and its schematic SpringRobocon2026_mainboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SpringRobocon2026 mainboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask KeioRoboticsAssociation before reusing the design.
