What is Keyball61

It is a self-made kit that aims to install a 100% user-friendly thumb trackball on a shoulder-friendly 60% left and right separated keyboard.

Each key is vertically staggered so that each finger can be naturally placed at the home position, and a 34mm trackball is attached near the thumb key, allowing mouse operation without disturbing the home position. is.

The easy-to-use index finger parenthesis key is provided, and the total number of keys is 61 on the left and right. You can use your thumb and index finger more by reducing the burden on your little finger.

The motion sensor is placed on the side of the ball to make it as thin as possible, so it does not get in the way even when the trackball is held in the palm of your hand.

The trackball holding case is injection molded and feels smooth to the touch. The precision is good, so it holds the ball well and does not fall even if the keyboard is turned upside down.

The reversible design allows left-handed users to switch the left and right boards to assemble and operate the trackball with the left hand.

In addition to the underglow, LEDs can also be mounted on the back of all keys except for the thumb keys (71 left and right total). The full-color LED (SK6812MINI-E) is not included in the kit, so please purchase it separately. A tabbed type is used for easy soldering.

The OLED module is mounted on both the left and right sides as standard.

It supports Kailh PCB sockets and can be hot-swapped with Cherry MX compatible switches. You can also change the thumb key only to Kailh Choc low profile switches to reduce the strain on your wrist.
