Questions
What parts does the FlightComputer CPU V1 use?
36 parts, built around the W25Q128JVPIQ. 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 CPU V1 KiCad files?
From the prxm-b/Modulex_CPU_PCB repository on GitHub, at the commit this page was made from: the board is FlightComputer_CPU_V1.kicad_pcb and its schematic FlightComputer_CPU_V1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FlightComputer CPU V1 design in my own project?
Its repository publishes it under the WTFPL licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
