Questions
How big is the Secukey PCB?
It measures 29 × 49 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Secukey use?
44 parts, built around the RP2350A, W25Q128JVSIQ, ABM8-272-T3 and ATECC608A-MAHDA-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 Secukey KiCad files?
From the Eladji/secukey repository on GitHub, at the commit this page was made from: the board is secukey.kicad_pcb and its schematic secukey.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Secukey design in my own project?
Its repository states no licence, so its author keeps all rights: ask Eladji before reusing the design.
