Design inspired by Neo Zelia
⚠️ Design-stage only, not even a working prototype.
Main features
- Swappable controller, aimed to be wireless with nice!nano
- Portable
- No plate
- No RGB
- Soldered switches

Layout
Standard 65% ANSI with exploded design.
Wiring
ProMicro has only 18 pins by default so wiring is a bit tricky as we need to stay in the limit. The most logical was to use 10 rows and 8 columns. Can be improved, probably.

Questions
How big is the Zzelia65 PCB?
It measures 330.2 × 100.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Zzelia65 use?
146 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 Zzelia65 KiCad files?
From the zzeneg/zzelia65 repository on GitHub, at the commit this page was made from: the board is kicad/zzelia65.kicad_pcb and its schematic kicad/adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Zzelia65 design in my own project?
Its repository states no licence, so its author keeps all rights: ask zzeneg before reusing the design.
