Descrição
A wireless split keyboard with hotswap and NO PCB.
- GitHub (files, firmware, docs):
- Build video
This is one of the simplest ways to get into custom keyboards without dealing with complicated PCBs or expensive kits.
You get full split ergonomics, or snap it together with magnets and run it as a compact 40% board.
Why this is different:
- No PCB required (fully handwired)
- Wireless (Nice!Nano / nRF52840)
- Hotswap (no soldering switches)
- Magnet system to combine both halves
- Actually buildable, not just a showcase
What you get:
- Fully printable case
- STEP files (edit / remix freely)
- Build manual + wiring guide
- ZMK firmware setup
- Full build video
