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.
- Large currents on controller board, which create differences in the ground voltage.
- 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.
- Singled ended control signals.
- 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.
