Questions
How big is the Flight Computer PCB?
It measures 80 × 22 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Flight Computer use?
43 parts, built around the W25Q128JVSIQ, SS54 and AO3400A. 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 Flight Computer KiCad files?
From the Sadcatt/Flight-Computer repository on GitHub, at the commit this page was made from: the board is Hardware/rev1/rev1.kicad_pcb and its schematic Hardware/rev1/Interface_and_debugging.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flight Computer design in my own project?
Its repository states no licence, so its author keeps all rights: ask Sadcatt before reusing the design.
