Questions
How big is the Flight Computer PCB?
It measures 93.7 × 43.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Flight Computer use?
113 parts, built around the CP2102-GMR, BMM150, BMP390 and SST25VF040B-50-4I-S2AE-T. 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 SunDevilRocketry/Flight-Computer repository on GitHub, at the commit this page was made from: the board is src/Flight-Computer/Flight-Computer.kicad_pcb and its schematic src/Flight-Computer/Connectors.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 SunDevilRocketry before reusing the design.
