Questions
How big is the Obc hardware PCB?
It measures 90.2 × 95.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Obc hardware use?
53 parts, built around the ADXL335BCPZ. 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 Obc hardware KiCad files?
From the SkCubeSat/obc-hardware repository on GitHub, at the commit this page was made from: the board is obc-hardware/obc-hardware.kicad_pcb and its schematic card-debug-board-2/card-debug-board-2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Obc hardware design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
