Questions
How big is the Hcrn PCB?
It measures 92.5 × 175 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hcrn use?
142 parts, built around the BMD-340-A-R, NAU8810YG, FDN360P and SP0503BAHTG. 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 Hcrn KiCad files?
From the DC801/DC27PartyBadge repository on GitHub, at the commit this page was made from: the board is Hardware/hcrn.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hcrn design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
