Product Overview

Our products are divided into five different categories:

See the tutorial for an explanation of how everything works together.


Master Brick DC Brick Stepper Brick Servo Brick IMU Brick

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 (Programming Interface). For the user, the stack behaves as if all Bricks were connected separately over USB with the PC. See the stacking tutorial for more information about stacks.

Bricklets can be used to extend the features of Bricks. There are Bricklets to measure physical quantity such as rotation, voltage, current and ambient light as well as Bricklets for control purposes such as switching relays, digital input/output and alphanumeric output on LCDs.

Unlike Bricks, Bricklets have no fixed size. Each Bricklet has the minimum size possible. Each Brick has up to four connectors for Bricklets.

On startup a Brick detects connected Bricklets. The Bricklet plugins, stored in the EEPROM of the Bricklet, are loaded into the flash of the Brick. This adds new functions to the Brick, that can then be used from the PC.

See Programming Interface for more information.

Master Extensions

Chibi Extension Ethernet Extension RS485 Extension WIFI Extension

For the Programming Interface concept, Master Bricks route messages between Bricks and the PC. To establish a connection between a PC and the Master Brick, typically the USB port is used. Master Extensions can be utilized to change the interface of a Master Brick. There are cable based and wireless Master Extensions available. From a programming perspective the different interfaces are transparent. A stack with Master Extension behaves as if every board in the stack would be directly connected to the PC over an USB connection.

This means: You can develop an application with all boards independently connected to the PC over USB. Later you can stack these boards together to stacks, add Master Bricks and cable based or wireless Extensions and you can run the previously written code without any changes.

Power Supplies

Step-Down Power Supply

A stack can be powered by the master of the stack over its USB connection. This option is limited by the USB specification to 500mA. A large stack may need more power than 500mA.

To provide greater currents, Power Supplies are available. These boards power the stack and can additionally be used to supply the power for driver Bricks (e.g. DC Brick). Power Supplies have the same size as Bricks and are stacked in at the bottom of the stack.
