Questions
How big is the PartyLine80 PCB?
It measures 100 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PartyLine80 use?
194 parts, built around the 1N5237B and SB140. 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 PartyLine80 KiCad files?
From the etherkit/PartyLine80 repository on GitHub, at the commit this page was made from: the board is PCB/PartyLine80.kicad_pcb and its schematic PCB/PartyLine80.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PartyLine80 design in my own project?
Its repository states no licence, so its author keeps all rights: ask etherkit before reusing the design.
