Wixel used with Arbotix Commander V2

This post in the Trossen Robotics Community forum shows a pair of Wixels are added to an Arbotix Commander V2 remote control, allowing it to send its signals to a computer. The author gives us a nice compliment:

Not to be a shill, but that was easier to set up than any MCU + Xbee configuration I’ve seen.
