littlebits Hardware Development Kit The Hardware Development Kit (HDK) is the quickest way to get started developing your own module for the bit Lab. The two proto modules allow you to connect to PCBs & breadboards, while the perf module means that you can build a small circuit right on the module. When you're ready to design your own PCB, you can use the included gray bit Snap™ connectors to attach to the board. We've also included color-coded stickers so you can easily denote your bit Snaps as power, input, wire, or output. Specifications
