Questions
How big is the Hh3.0 PCB?
It measures 47.1 × 17.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hh3.0 use?
17 parts. 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 Hh3.0 KiCad files?
From the Addwaaait/Green_Nodes repository on GitHub, at the commit this page was made from: the board is hh3.0/hh3.0.kicad_pcb and its schematic hh3.0/hh3.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hh3.0 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
