README
Nemui/NemuiPCBfiles/README.mdNemui
This is the open source PCB modified for the Nemui Keyboard. This PCB was designed by Aeternus.
It's minimally designed (as intentioned) with bare minimum support.
These files are provided as-is and are intended for tinkerers, do not expect warranty or support to be provided.
Ordering
The files needed to produce the pcb are in the production/ folder.
Todo for a v2 pcb
- More layout support, iso/7u/3-1-3
- LED @ top right blocker
- JST instead of usb-c

Questions
How big is the Nemui PCB?
It measures 304.8 × 99.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nemui use?
167 parts, built around the SRV05-4, 1N4148W, DTC123JE and RB060M-60TR. 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 Nemui KiCad files?
From the cBachoo/bachooKeyboardFiles repository on GitHub, at the commit this page was made from: the board is Nemui/NemuiPCBfiles/Nemui.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nemui design in my own project?
Its repository states no licence, so its author keeps all rights: ask cBachoo before reusing the design.
