Questions
How big is the Kizuna band PCB?
It measures 72 × 27.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kizuna band use?
10 parts, built around the DFR0299. 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 Kizuna band KiCad files?
From the TomatoCakePasta/highTouch_device repository on GitHub, at the commit this page was made from: the board is kizuna_band/kizuna_band.kicad_pcb and its schematic kizuna_band/kizuna_band.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kizuna band design in my own project?
Its repository states no licence, so its author keeps all rights: ask TomatoCakePasta before reusing the design.
