Pixel controllers are used to control smart LED pixels or strips. Each port on the controller is used to control a string or strip of varying length. All pixel controllers can handle 5V and 12V strips.
The Pixie controllers (4, 8 and 16 ports) are designed as an economical solution for use on Light-O-Rama Networks. They do not support DMX. If your show is controlled by Light-O-Rama running on a PC or a Gen3 director then the Pixie is a great and inexpensive way to control a lot of pixels.
The PixCon16 controller can run on a LOR network or Ethernet. If you use products other than Light-O-Rama to control your show you will need a PixCon16.
