Questions
How big is the Kicad Cansat PCB?
It measures 39.7 × 48.2 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Kicad Cansat use?
84 parts, built around the BMP581, TPS54233D, BNO055 and B230A. 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 Kicad Cansat KiCad files?
From the Mathou7/2627_Projet2A_Cansat repository on GitHub, at the commit this page was made from: the board is Hardware/Kicad Cansat-V1.1/Kicad Cansat.kicad_pcb and its schematic Hardware/Kicad Cansat-V1.1/Kicad Cansat.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kicad Cansat design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mathou7 before reusing the design.
