The wireless receiver 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 bit can receive a signal at a distance of about 100 feet 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.

Check out our Tips + Tricks for more ideas on using the wireless receiver. New! Updated wireless bits, with 5 channel functionality, are available in the Gizmos and Gadgets Kit.

Harper X. ★★★★★

Setting up a remote trigger for my circuit took maybe ten seconds once the channel dials matched on both ends. The five channels mean I can run a few separate builds without them stepping on each other, which is exactly what I needed. Range is solid across my whole workbench, no dropouts so far.

Eva W. ★★★★☆

Paired this with the transmitter to trigger my motors from across the room, and it works fine on channel 3. Only gripe is that the receiver needs its own power bit to run, which I didn't realize at first.
