Questions
How big is the Jig2 PCB?
It measures 40 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Jig2 use?
23 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 Jig2 KiCad files?
From the OpenEPaperLink/Hardware repository on GitHub, at the commit this page was made from: the board is 2.9 Flasher by Jonas/jig2.kicad_pcb and its schematic 2.9 Flasher by Jonas/jig2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Jig2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask OpenEPaperLink before reusing the design.
