Questions
How big is the Leviosa PCB?
It measures 38.2 × 11.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Leviosa use?
59 parts, built around the ATTINY13A-PU, MCP6001R-I/OT, MX27517 and SS495A. 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 Leviosa KiCad files?
From the Kay-Jack/Leviosa repository on GitHub, at the commit this page was made from: the board is PCB/P3/Leviosa/Leviosa.kicad_pcb and its schematic PCB/P1/Leviosa/Leviosa.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Leviosa design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kay-Jack before reusing the design.
