I have removed noticeable flux residue as much as possible with anhydrous ethanol, but I would appreciate it if those who understand DIY keyboards would purchase it.

I am selling it because I was able to obtain the roBa I originally wanted.

About Keyball39

A DIY keyboard kit that aims for a compact, split keyboard with a minimal number of keys and a 100% usable thumb trackball.

It adopts a column-staggered layout that shifts each key vertically so that each finger can be placed naturally in the home position, and by placing a 34mm trackball near the thumb keys, mouse operation is possible without breaking the home position.
Although it is very compact with a total of 39 keys, it has enough thumb keys and bottom row keys, and a variety of Modify keys can be assigned. Also, the key layout on the side without the trackball is similar to a number pad.

A motion sensor is placed on the side of the ball to make it as thin as possible, and it does not get in the way even if the trackball is contained in the palm of your hand.

OLED modules are standard on both left and right sides.

Compatible with Kailh PCB sockets, Cherry MX compatible switches can be used with hot-swappable functionality. You can also change only the thumb keys to Kailh Choc low profile switches to reduce the burden on your wrists.
