Questions
How big is the Bonsai PCB?
It measures 348.5 × 165.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bonsai use?
204 parts, built around the ATMEGA32A-PU. 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 Bonsai KiCad files?
From the Retne01/Bonsai repository on GitHub, at the commit this page was made from: the board is Bonsai.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bonsai design in my own project?
Its repository states no licence, so its author keeps all rights: ask Retne01 before reusing the design.
