Questions
How big is the Kryptonite PCB?
It measures 26.3 × 17.1 mm and has 2 copper layers, 0.79 mm thick.
What parts does the Kryptonite use?
27 parts, built around the STM32F072CBU6, ATECC608B-MAHDA-S, MCP1700T-3302E/TT(MS) and USBLC6-2SC6. 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 Kryptonite KiCad files?
From the samienr/kryptonite repository on GitHub, at the commit this page was made from: the board is kryptonite.kicad_pcb and its schematic kryptonite.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kryptonite 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).
