Important Notes

• 3D-printed cases may have minor layer lines or surface texture variation — this is normal for FDM printing and not a defect.
• This is a compact 3x6 split layout. An adjustment period is normal if you are new to split keyboards.
• Trackball sensitivity may feel different from a regular mouse.
• Use standard 5V USB charging only. Fast chargers are not supported.
• Warranty does not cover firmware modifications, incorrect assembly, improper charging, or misuse.

The ZMK 3x6 Compact is the most minimal trackball split keyboard in the Artkeeb lineup. At 3x6 keys per half, it strips the layout down to the essentials — every key is within reach of the home position, and layers handle anything that doesn't fit on the base layout.

This is the keyboard for desk workers who want to go as small as possible without losing functionality. The compact footprint leaves significant desk space open, and the built-in trackball means no mouse pad or separate pointing device is needed.

ZMK firmware provides wireless Bluetooth connectivity between the two halves and to your computer. Power management is excellent — the keyboard's sleep behavior is optimized to maximize battery life without sacrificing responsiveness when you return to typing.

Hot-swap sockets throughout. Change switches anytime without soldering.

Ships fully assembled and firmware-loaded. Ready to use immediately after pairing.

Ideal for programmers, writers, and anyone who wants the smallest possible keyboard footprint with full cursor control built in.
