Questions
How big is the FlightComputer PCB?
It measures 90 × 90 mm and has 4 copper layers, 4.69 mm thick.
What parts does the FlightComputer use?
83 parts, built around the STM32F103VCT6, SN74LVC2G04DCKR, USBLC6-2SC6 and ABM3B-8.000MHZ-10-1-U-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 FlightComputer KiCad files?
From the jbrown3859/EE175-SeniorDesign repository on GitHub, at the commit this page was made from: the board is hardware/FlightComputer/FlightComputer.kicad_pcb and its schematic hardware/FlightComputer/FlightComputer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FlightComputer design in my own project?
Its repository states no licence, so its author keeps all rights: ask jbrown3859 before reusing the design.
