Questions
How big is the MainBoard PCB?
It measures 140 × 97 mm and has 4 copper layers, 1.62 mm thick.
What parts does the MainBoard use?
137 parts, built around the SC0914(13), 74LVC1G07SE-7-MS, W25Q128JVSIQ and ICM-42688-P. 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 MainBoard KiCad files?
From the Immortals-Robotics/MainBoard repository on GitHub, at the commit this page was made from: the board is main-board.kicad_pcb and its schematic can.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MainBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Immortals-Robotics before reusing the design.
