Please do not flash or modify the firmware unless you have ZMK experience.

Important Notes

• This is a compact layer-based layout. An adjustment period is normal if you're new to split keyboards.
• 3D-printed cases may have minor surface texture variation — this is expected.
• Use standard 5V USB charging only. Fast chargers are not supported.
• Warranty does not cover firmware modifications, incorrect assembly, or misuse.

The Wireless Split Trackball Keyboard is a prebuilt, ready-to-use ergonomic keyboard that combines wireless freedom with built-in cursor control. No mouse required. No cables required. Just two keyboard halves, a built-in trackball, and a completely uncluttered desk.

ZMK firmware manages the wireless connection between the two halves and the Bluetooth connection to your computer. Battery life is excellent — ZMK's power management is built for efficiency, and the keyboard sleeps aggressively when idle to extend time between charges.

The trackball is positioned at the thumb cluster, where your thumb naturally rests while typing. Rolling the ball moves the cursor; dedicated buttons handle clicking and scrolling. After an adjustment period of a few weeks, switching between typing and cursor control becomes seamless.

Hot-swap MX sockets let you swap switches without soldering. The keyboard ships with switches pre-installed, but you can change them at any time.

Fully assembled and tested before shipping. Firmware preloaded — no configuration required to start typing and using the trackball on day one.

Compatible with Mac, Windows, and Linux via Bluetooth.
