Questions
How big is the Cpu flex PCB?
It measures 22 × 10.8 mm and has 2 copper layers, 0.12 mm thick.
What parts does the Cpu flex use?
9 parts, built around the AON7506. 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 Cpu flex KiCad files?
From the floxcap/fly2040 repository on GitHub, at the commit this page was made from: the board is pcb/cpu_flex/cpu_flex.kicad_pcb and its schematic pcb/cpu_flex/cpu_flex.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cpu flex design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
