Every SAM module has a built in wireless chip, which means that each module doesn’t have to actually be connected directly to the others. The magnetic system of littleBits is great, but there are always times when then become disconnected. With SAM, children can run around the room without their system unclipping or disconnecting.
This also decreases the overall cost of the system as there’s no need for additional modules that enable wirelessness or extension wires
