Buildings can also be modified with modules that are chips which modify the functionality of a building. These modules cannot be purchased however, as they are only obtainable through means like crafting or rejuvenating.

Droppers mine ores from different veins underground. The mined ores are dropped onto conveyor belts that transport them to different parts of your setup.
