WS2814A LED strip light
ws2814a led strip light is a pixel rgbw led strip light which is equipped with brand ws2814a IC. Normally, the voltage is DC 24V and 6leds/pixel. This allow ws2814a led strip to reach Colorful light effects like monochrome, gradient, water, horse racing, text, numbers, chase, English, pictures, animations, video, etc.
With same function, there are also IC tm1814 led strip, ucs2904b led strip, sm16704 led strip. You can just choose the type which you love.

FAQS
The data protocol adopts a single line return to zero code communication method. After the chip is powered on and reset, the DIN end receives the data transmitted from the controller. The first 32bit data sent is extracted by the first chip and sent to the data latch inside the chip. The remaining data is processed and amplified by the internal shaping circuit, and then transmitted to the next cascaded pixel through the DO port. After each pixel transmission, The signal is reduced by 32 bits. The chip adopts 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.
The data latch inside the chip generates different duty cycle control signals at the OUTR, OUTG, OUTB, and OUTW control terminals based on the received 32bit data. When waiting for the DIN terminal to input the RESET signal, all chips synchronously send the received data to each segment. The chip will receive new data after the signal is bundled, and after receiving the initial 32bit data, it will forward it to the data port through the DO port, Before the chip receives the RESET code, the original output of the OUTR, OUTG, OUTB, and OUTW pins remains unchanged until it reaches 280 μ After the low-level RESET code above s, the chip outputs the 32bit PWM data pulse width just received to the OUTR, OUTG, OUTB, and OUTW pins.
Provide 8 SOPs
main features
1) R, G, B, W output ports withstand voltage of 20V, and DIN ports withstand voltage of 9V.
2) The chip is equipped with a built-in voltage regulator, and 24V and below power supplies only need to connect a resistor to the IC VDD pin, without the need for an external voltage regulator.
3) Built in signal 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.
5) The PWM control terminal can achieve 256 levels of adjustment, with a scanning frequency of 2KHz.
6) Serial cascade interface, capable of receiving and decoding data through a single signal line.
7) There is no need to add any circuit when the transmission distance between any two points does not exceed 5 meters.
8) The color of light is highly consistent and cost-effective.
9) When the refresh rate is 30 frames/second, the number of cascades should not be less than 1024 points.
10) The data transmission speed can reach 800Kbps.
Main application areas
1) LED full color luminous character light string, LED full color soft light strip hard light strip, LED guardrail tube.

ws2814 led strip is better than tm1814 sm16704 ws2814a led strip
On the basis of TM1814/SM16704/WS2814A magic light strip, there is also WS2814 RGBW magic light strip now. WS2814 IC is equivalent to the upgraded version of TM1814/SM16704/WS2814A. It has all the performance of this ordinary RGBW, plus an additional breakpoint. With the function of resuming transmission, the damage to a single IC does not affect the quality of the subsequent light strips, so the performance is more stable.
