Lighting Elements. Every LED is integrated with a small microcontroller…

The early prototype devices were:

• 22mm x 9mm
• individually addressable
• self-addressing
• powered and controlled through a two conductor powerline network
• topology independent
• 30 frames per second update
• only four hardware components…

Control Elements. Interconnect networks of lighting elements to form larger displays.

• 500kbps uplink
• daisy chained
• form hierarchies to scale
• current sensed output
