From Paragon Wiki
The Corner Terminal is one of the smaller, entry-level Tech Auxiliary Base Control Items.
Slightly more powerful than its smaller cousin, the Terminal, it is also commonly used as a small addition to generate some extra control for a small base at a cheap price, or to top-off the needs of a medium or larger base when there is a need for just that extra little more.
Another Tech item that can be purchased to generate Control for a Base. This item can only be attached to another item.
