Questions
How big is the Kaizen PCB?
It measures 284.2 × 102.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kaizen use?
135 parts, built around the STM32F072CBT6. 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 Kaizen KiCad files?
From the AzYN-toro/kaizen-pcb repository on GitHub, at the commit this page was made from: the board is Kaizen.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kaizen design in my own project?
Its repository states no licence, so its author keeps all rights: ask AzYN-toro before reusing the design.
