LittleBits was built to break down the barriers between the products we consume and the things we make, to make everyone into an inventor. these modules are designed to work with the Littlebits Kits
There are over 50 Littlebits modules in the making, divided into 4 categories: power, input, output, wire. littleBits is an open source project, and detailed circuit diagrams can be downloaded from the Littlebits GitHub repository.
