Direct Wiring

This is the least expensive method to drive smart pixels is with a large power supply powered through your controller. The only other components required is a power cable to the pixels. It is recommended that you use 16AWG extension wire in lengths of 10-15 feet, which is cheapest bought as an extension cord.

Pros:

  1. Inexpensive
  2. Simple

Cons:

  1. Large currents on controller board, which create differences in the ground voltage.
  2. The signal and power share the same ground, which means that the voltage drop due to the power current affects the reference ground for the control signal.
  3. Singled ended control signals.
  4. Large wire gauge and connectors on the controller.

This method is not recommended, but it works since the average current to the LED’s is much lower than the maximum.
