3535 series led lamp beads: Top SMD integrates high-quality external control single-wire serial cascade constant current IC, the control circuit and RGB chip are integrated in SMD 3535 components, forming a complete external control pixel point, the color mixing effect is uniform and consistent Sex is high. Built-in data shaping circuit, any pixel receives the signal after waveform shaping and then outputs it to ensure that the line waveform distortion will not accumulate. Built-in power-on reset and power-off reset circuits, grayscale adjustment circuit (256-level grayscale adjustable) when power-on does not light.

      The red light drive is specially processed, the color matching is more balanced, and the single-line data transmission can be cascaded infinitely. Shaping and forwarding enhancement technology, the transmission distance between two points exceeds 10M, the data transmission frequency can reach 800Kbps, and when the refresh rate is 30 frames/second, the number of cascades is not less than 1024 points. In addition, a voltage-stabilizing current-limiting resistor needs to be connected in series with the external power supply to prevent the IC from being damaged by reverse connection of the power supply.
