Questions
How big is the HPV Riser PCB?
It measures 200 × 47 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HPV Riser use?
7 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 HPV Riser KiCad files?
From the demik/oldworld repository on GitHub, at the commit this page was made from: the board is EDA/HPV Riser/HPV_Riser.kicad_pcb and its schematic EDA/68k-nano+/68000sbc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HPV Riser design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
