Product Overview:

SK6812SMINI-ER-001 is an intelligent external LED light source that integrates control circuits and light emitting circuits. Its appearance is the same as a SMD3528 top emitting LED bead, with each component being a pixel. The interior of the pixel contains an intelligent digital interface data locking signal shaping and amplification driving circuit, a power supply stabilizing circuit, a built-in constant current circuit, a high-precision RC oscillator, and the output driver adopts patented PWM technology, effectively ensuring high color consistency of the light inside the pixel.

The data protocol adopts a unipolar return to zero code communication method. After the pixel is powered on and reset, the DIN terminal receives the data transmitted from the controller. The first 24bit data sent is extracted by the first pixel and sent to the data latch inside the pixel. The remaining data is processed and amplified by the internal shaping circuit, and then forwarded and output to the next cascaded pixel through the DO port. After each pixel transmission, The signal is reduced by 24 bits. Pixel points adopt automatic shaping and forwarding technology, so that the number of cascaded pixels is not limited by signal transmission, only limited by signal transmission speed requirements.

LED has the advantages of low voltage driving, environmental protection and energy conservation, high brightness, large scattering angle, good consistency, ultra-low power, and ultra-long lifespan.

Integrating the control circuit onto the LED makes the circuit simpler, smaller in size, and easier to install.

Characteristic description:

1. TopSMD internally integrates high-quality external control single wire serial cascade constant current IC

2. The control circuit and chip are integrated into the SMD 3528 component to form a complete external control pixel, with uniform and consistent color temperature effect

3. Built in data shaping circuit, any pixel receives a signal and undergoes waveform shaping before outputting, ensuring that line waveform distortion does not accumulate

4. Built in power on reset and power off reset circuits, no light on when powered on

5. Grayscale adjustment circuit (256 levels of grayscale adjustable)

6. Special treatment for red light drive, more balanced color matching

7. Single line data transmission with infinite cascading capability

8. Shaping forwarding reinforcement technology, with transmission distance between two points exceeding 10M

9. 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
