Product Overview
This is a custom keyboard kit (switches, keycaps, and Type-C cable not included). Built on the ZMK firmware, it shares the same firmware and codebase as our MX-version Corne, ensuring reliable performance and extensive customization. It supports dual-mode connectivity (Bluetooth/USB) with multiple device pairing, and an optional 2.4G receiver will be available by the end of February.

Key Features
-
Flexible Layout – PCB allows removing 6 keys per side, converting it into a Corne 3x5 layout (case under development).
-
Battery Performance – Powered by a 180 mAh (tested 200 mAh) battery, offering ~166 hours runtime. With auto-sleep, real-world use extends to 20–30 days.
-
Hot-Swappable Sockets – Supports Kailh Choc V1 / V2 (1353) switches, using Kailh 1350 hotswap sockets for easy replacement.
-
Controls – Default knob function: volume adjustment. Joystick: arrow keys and mouse pointer control (for emergencies, not a full replacement for a mouse).
-
Ultra-Thin Design – Only 1 mm thickness under the hotswap socket, plus 0.6 mm recessed anti-slip feet, adding just 0.4 mm overall. Comes with 2 mm feet by default, with optional replacements (1mm/1.5mm/2mm).
-
Safety-Oriented Build – Avoids exposed sockets to reduce short-circuit risks from liquid spills.
Additional Notes
-
For users who prioritize thinness, the no-knob, no-joystick version is recommended.
-
Preloaded with ZMK Studio for key remapping; advanced users can recompile firmware via GitHub (repo: github.com/a741725193/zmk-corne).
-
Reset button located in the rear circular hole (double-tap to enter BL mode). Thumb-side toggle switches act as battery switches (down = on).
