Tinkerforge Bricks

Bricks are 4 x 4cm (1.57 x 1.57") boards equipped with a preprogrammed 32-bit ARM microcontroller, a Mini-USB port, two status LEDs, connectors for stacking and up to four connectors for Bricklets. There are Bricks that perform complex sensor tasks (e.g. IMU Brick), communicate (e.g. Master Brick) and drive motors (e.g. DC Brick).

Bricks can be assembled into a stack. A Master Brick at the bottom of a stack is responsible for the communication all boards within the stack. This master routes the messages between the boards in the stack and the PC. For the user, the stack behaves as if all Bricks were connected separately over USB with the PC.
