Modules

Modules are a type of item in Astroneer that allows players to advance in the game by crafting resources, providing bytes, or cleaning up debris found on the planets. They vary in size, from small to extra large, and need to be placed on the proper Attachment Slot to function. Widgets are a special type of small module which can also be used while attached to one of the two widget slots in an Astroneer's backpack.

Some modules are available early on, e.g., all Printers are unlocked at the very start of a save. Others have to be unlocked in the Research Catalog at the cost of Bytes. As all items created by the player, they have to be printed at an appropriate printer. Some modules can also be found as part of Discoveries.
