Questions
How big is the Superlyra hs PCB?
It measures 390.8 × 134.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Superlyra hs use?
212 parts, built around the ATMEGA32U4-MU and SRV05-4. 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 Superlyra hs KiCad files?
From the Malevolti/SuperLyra repository on GitHub, at the commit this page was made from: the board is pcb/hotswap/superlyra-hs.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Superlyra hs 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).
