🔹 Important Notes

This keyboard uses ZMK firmware and is not a VIA keyboard.

The standard listing does not include a USB-C cable.

RGB backlight is supported, but using RGB may reduce battery life, as it consumes more power on wireless keyboards.

The case is 3D printed, so minor layer lines or surface texture may be visible. This is normal for custom 3D printed keyboard cases.

The OLED display position may not be perfectly centered due to the internal layout, hot-swap socket placement, and structural design.
