4 RGB LED Module

Overview

Smart reverse polarity protection, reverse power supply will not damage the IC.
IC control circuit and LED point light source common a power supply.
Control circuit and RGB chip integrated in a 5050 package components, constitute a complete external control pixel.
Built-in signal shaping circuit, any one pixel after receiving the signal waveform shaping and then output to ensure that the waveform distortion will not be accumulated line.
Built-in power-on reset and power-down reset circuit.
Three primary colors of each pixel can achieve 256 levels of brightness display, complete 16777216 colors of the true color display, scanning frequency of not less than 400Hz / s.
Serial cascade interface, through a signal line to complete the data reception and decoding.
Any two-point transmission distance no more than 5 meters without adding any circuit.
When the refresh rate is 30 frames per second, the concatenation number is not less than 1024 points.
The color of the light is highly consistent and cost-effective.
