This item is under development, and it's expected to ship in July. Please subscribe to our monthly newsletter, so we can keep you updated. If you pre-order this item along with non-module items, we'll ship it separately from non-module items later, and we'll absorb its separate shipping fee. If you have pending module orders, our webshop will charge for shipping which we'll reimburse after shipping the modules.
The key cluster module attaches to the left keyboard half, and it features three regular keys, two buttons and a mini trackball which can also be pressed – acting as an extra button. Following is a demonstration of our latest key cluster and trackball module prototypes.
