Questions
How big is the Higonokami PCB?
It measures 14 × 29.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Higonokami use?
23 parts, built around the STM32F103CBT6 and BC857. 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 Higonokami KiCad files?
From the EasyAppSecurity/gnuk-portable-pcb repository on GitHub, at the commit this page was made from: the board is higonokami.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Higonokami design in my own project?
Its repository states no licence, so its author keeps all rights: ask EasyAppSecurity before reusing the design.
