After the Ascend, Kai H. Chang shared his Kai Simple, an all-Choc low-profile wireless split.
I've been using my last Ascend KB for a month. While it is comfortable, MX switches are still relatively big and wide. Maybe it's bc I have small hands or was used to Sweep before it, I started missing Chocs, so that's why there's this Simple – Kai.
After the combined approach of the Ascend (MX switches for the main area and Chocs for the thumb keys), the author went with an all-Choc design this time.
Saving desk space was still one of the design goals, but while aiming for ZMK/wireless, Kai left a pin for TRRS connectors.
Specs
- 34 keys
- Choc switches, soldered
- Pro Micro footprint
- ZMK
The design of the Ascend was inspired by the Wubbo.
Again, the keycaps are KLP Lamé by braindefender.
