littleBits makes an open source library of electronic modules that snap together with tiny magnets for prototyping, learning, and fun.

littleBits consists of tiny circuit-boards with specific functions engineered to snap together with magnets. No soldering, no wiring, no programming, just snap together for prototyping, learning and fun. Each bit has a specific function (light, sound, sensors, buttons, thresholds, pulse, motors, etc), and modules snap to make larger circuits.

The mission of littleBits is to create the next generation of problem-solvers, and interventions. The time is ripe to create the pipe cleaner and the popsicle stick of the 21st century.

Open innovation is enabling these new problem solvers. littleBits uses open source technology and is building a community of contributors who experiment, share online, and learn from each other’s creativity. Their designs are publicly available so that anyone can see and use them. These designs are available at:
