Questions
How big is the Cubesat obc PCB?
It measures 92 × 88.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Cubesat obc use?
311 parts, built around the STM32L552ZET6Q, TLE9250XLE, MMC5983MA and STSPIN240. 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 Cubesat obc KiCad files?
From the ephemeridis/cubesat_obc repository on GitHub, at the commit this page was made from: the board is obc_board/cubesat_obc.kicad_pcb and its schematic adapter_board/adapter_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cubesat obc 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).
