These RGB (Smart Pixel) Controllers come fully assembled (mounted in an enclosure with a power supply connected)

Pixie controllers are a simpler-to-use (onboard DIP switches) that can connect to an ELOR network via USB485 Adapters or a Director, or be used with a Pixielink (which converts standard E1.31 (streaming ACN) into six RS485 output networks).

The Aurora Core is an advanced E1.31 controller, connected to your Computer or Touch Player via ethernet port. 

In order to connect to pixels, the assembled controller must have an installed dangle (or "pigtail"). The LOR or Xconnect type dangles refers to the shape/size of the connection pins. Your dangles, extensions, and pixels all must be the SAME type, or you will need an adapter.
