Questions
How big is the Zenith PCB?
It measures 50.8 × 43.5 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Zenith use?
10 parts, built around the RX5808. 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 Zenith KiCad files?
From the grimsteel/zenith repository on GitHub, at the commit this page was made from: the board is pcb/zenith.kicad_pcb and its schematic pcb/zenith.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Zenith design in my own project?
Its repository states no licence, so its author keeps all rights: ask grimsteel before reusing the design.
