littleBits wireless receiver

The wireless receiver module receives a signal from your wireless transmitter 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 receive a signal at 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.
