Features of SK6812:

1) SK6812 has the same function as WS2812B with built-in IC that could be independently addressable, with extra white channel, you can set them to any color or animation you want

2) SK6812 support many controllers such as Arduino, FastLED library, Raspberry Pi, Fadecandy, T1000S, K1000C etc

3) 30leds 60leds 72leds and 144leds per meter are available for option.

4) 32-bit color control (8-bit PWM per channel);

5) Designed with 3pin JST-SM connectors on both ends for easy connection


SK6812 LED Strip Applications:

1) Widely used for home decoration use like hotels, clubs, shopping malls

2) KTV Bar Amusement decoration lighting.

3) Advertising sign illumination

4) Decorative lights for holiday, event, show exhibition

5) Applicable for automobile and bicycle decoration, border or contour lighting


Advantage and disadvantage of TM1814


TM1814 advantages

1.Up to 32V, allowing long cable lengths

2.High PWM rates allow these pixels to be captured with cameras up to 34fps

3.The presence of white LEDs allows for higher brightness and more color mixing options


TM1814 disadvantages

1.Data-only limit The refresh rate is limited by the speed of the protocol, which is generally slower

2.Only 8 bits of data per color makes the dimming curve less smooth

3.No data redundancy


Advantage and disadvantage of SK6812


SK6812 advantages

1.The high PWM rate of 1.20KHZ allows to capture pixels at 30fps.

2.Driving 4-color LEDs enables hues that were previously difficult to achieve with a single RGB strip.

3.RGB and white can be controlled independently, allowing us to create bolder, more vibrant colors than RGB alone.

4.Integrated with 5050 LEDs, it can provide high-density single-control RGBW light strips.


SK6812 disadvantages

1.8-bit color resolution, 256 levels of grayscale per color, making the dimming curve less smooth.

2.The refresh rate of the No Clock data line is limited by the speed of the protocol, which is generally slower.

3.Compared to external IC chip solutions, integrated LEDs have poor heat dissipation capabilities.

4.Limited to 5V, greater voltage drop.
