The littleBits Extended Kit is currently sold out, but you can still find a great assortment of Bits in our Starter Kit!

The Extended Kit is the best way to take your interactive projects to the next level! We handpicked 14 of the most fun, mechanical Bits and crammed them into one double-decker kit, while making sure that they’re a great complement to the Starter Kit. But it’s not just for Starter Kit owners: it has everything you need to get started, including a bit that powers your littleBits from a computer’s USB port or with a 9V battery, for a variety of power options.

The Extended Kit also includes an Instruction Sheet with several project suggestions. And, if you ever stop playing, you can pack everything away in the sleek rectangular case.

The Extended Kit contains:

  • A quick-start instruction set
  • A micro USB cable to power your littleBits from a computer
  • A 9V battery, cable and power bit for untethered power
  • 14 littleBits
