Questions
How big is the LEOS flight computer PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LEOS flight computer use?
38 parts, built around the MCP2562FD-E/P, MCP2518FDT-E/SL-HX, SAM-M8Q-0 and CRCW0805130RFKEAC. 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 LEOS flight computer KiCad files?
From the VIP-LES/flight-computer-pcb repository on GitHub, at the commit this page was made from: the board is LEOS-flight-computer.kicad_pcb and its schematic LEOS-flight-computer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LEOS flight computer design in my own project?
Its repository states no licence, so its author keeps all rights: ask VIP-LES before reusing the design.
