Questions
How big is the Jeopardy hw PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Jeopardy hw use?
13 parts, built around the RJ45 and ULQ2003A. 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 Jeopardy hw KiCad files?
From the entropia/jeopardy-helmets repository on GitHub, at the commit this page was made from: the board is hardware/jeopardy-hw.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Jeopardy hw design in my own project?
Its repository states no licence, so its author keeps all rights: ask entropia before reusing the design.
