You will need a wireless receiver and a transmitter to use littleBits wirelessly. You can purchase additional receivers and transmitters, but if you are just getting started with littleBits wireless modules, we suggest purchasing the Wireless Boost It.
The wireless transmitter sends a signal to your wireless receiver and activates your littleBits circuit remotely! The three channels (labeled 1, 2, and 3) on the transmitter and receiver correspond to each other and can be used simultaneously. The module can transmit its signal to a distance of about 100’ indoors. Multiple wireless receivers can be used with a single wireless transmitter, but only one wireless transmitter can be used in proximity to another wireless transmitter.
