Questions
How big is the QSPIBuddy PCB?
It measures 65 × 56.5 mm and has 4 copper layers, 1.66 mm thick.
What parts does the QSPIBuddy use?
46 parts, built around the SY6280AAC, TMUX1574PW, LM66100DCK and SRV05-4. 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 QSPIBuddy KiCad files?
From the Manawyrm/QSPIBuddy repository on GitHub, at the commit this page was made from: the board is qspibuddy.kicad_pcb and its schematic qspibuddy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the QSPIBuddy 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).
