Modules are one of the main types of items in Astroneer. All crafted at Printers and used in base construction and functionality are considered Modules, each categorized by size or to which Attachment Slot they snap to.

Modules function in a variety of ways, from platforms which can hold other items, to Solar Panels which generate power. Some smaller modules, when placed on the ground, will provide their own attachment slot in the form of a Small Platform and can also be used in the backpack of a player, like a Small Solar Panel. Modules that the player can place or activate from their backpack or when placed on the ground are categorized as Deployables.

Not all modules are available to the player when starting a new game. To unlock new modules, the player must perform research to earn Bytes, which can then used to purchase new module Schematics from the Research Catalog. More advanced modules typically cost more Bytes to unlock.

Tier 1 - Small

Tier 1 modules are the smallest classification of modules, occupying a single Attachment Slot. They are also the most diverse in terms of how and where they can be deployed for use. With the exception of Crates, Tier 1 modules are created using the Backpack Printer.

Widgets are Small modules that can be carried in the backpack and generally have some manner of active behavior when plugged into a widget-compatible slot.
