B-Squares (Arduino compatible-SQUARE)

B-Squares is a 3D modular electronics system with an emphasis on solar power and expandable energy storage, enabling the hobbyist to prototype clean-tech and Arduino inventions faster than ever before.

The Squares have magnetic contacts on each corner which allow them to easily snap together without wires. These magnetic contacts are also used to transmit electric signals between the Squares. This design allows users to quickly assemble Squares into arrays, with power flowing through the array, without wiring or soldering. The Arduino-Square includes a 3.3V Arduino Pro compatible microcomputer with easy access to the shield ports.
The Software necessary to program the Arduino-Square can be found here http://arduino.cc/en/Main/Software
You will also need a serial-to-USB connector to connect the Arduino-Square to a PC.
