Why No RGB?
RGB lighting is intentionally excluded on this Bluetooth version. RGB significantly increases battery consumption, which reduces wireless battery life. Keeping it off means longer use between charges for a cleaner wireless experience.
Important Notes
- Bluetooth ZMK only. This is not a QMK/VIA version. Wired VIA remapping is not supported.
- The Corne layout has no number row and uses layers for numbers and symbols. An adjustment period is normal if you are new to compact layouts.
- Battery may not be included due to international shipping restrictions. Please check with us before ordering if this is a concern.
- Product photos are for reference. Slight color variation may occur due to lighting and production batches.
- Warranty does not cover switch replacement damage, firmware modifications, or misuse.
