Bricks are 4 x 4cm (1.57 x 1.57") modules that can be controlled by devices, such as (embedded) PCs, over their Mini-USB connector. Every Brick basically performs one task. There are Bricks that perform complex sensor tasks (e.g. IMU Brick 2.0), communicate (e.g. Master Brick) and drive motors (e.g. DC Brick).
With Bricklets the features of Bricks can be extended. Dependent on the Brick it has two or four connectors for Bricklets.
Bricks can be assembled into a stack (see description of stack concept). The USB interface of a Master Brick can be replaced by Wi-Fi, Ethernet or RS485 with Master Extensions. In conjunction with the stack concept all Bricks and Bricklets can be controlled by Wi-Fi or Ethernet instead by USB.
