There are over 50 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 our GitHub repository.
Bits with blue connectors are the ones that provide the juice to get you up and running! You’ll need one of these Power Bits in every creation you make.
Input Bits are pink. They are buttons, switches and sensors: the eyes + ears of the system. They interpret their surroundings to make things happen.
Orange Bits are Wire Bits that help you extend + branch out. You don’t always need one, but they give you options for linking and adding intelligence to your creations.
