Questions
How big is the UKey STM32 PCB?
It measures 36.8 × 22.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UKey STM32 use?
22 parts, built around the M25PX32-VMW6E and NUF2221W1. 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 UKey STM32 KiCad files?
From the imi415/UKey_STM32 repository on GitHub, at the commit this page was made from: the board is UKey_STM32.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the UKey STM32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask imi415 before reusing the design.
