Each LED board contain 3 basic parts: LED module, controller, power supply

LED module

since traditionally LEDs when leaves in sunlight for long time loss its first brightness, so

that modules make by special LEDs that have higher resistance to sun ray.
 

Controller

Power supply
power supply is a 5v regulated adapter and its current is between 1A to 50A or more (according to number of modules that make bigness of display)
Note: connecting + and - in reverse causes damage for both controller and LED modules.
