SK9822(Similar to APA102) RGB 144LEDS/M DC5V 12MM-Wide Digital Intelligent Addressable LED Strip Lights - 1m/3.28ft per roll

Features

1. There are 144 Addressable RGB LEDs per meter,  and 12mm wide for 144 LEDs/meter, DC5V input, and you can control each LED individually!  This is the digitally-addressable type of LED strip. You can set the color of each LED's red, green and blue component with 8-bit PWM precision (so 24-bit color per pixel).

2. The LEDs are controlled by shift-registers that are chained up down the strip so you can shorten or lengthen the strip.

3. The PWM is built into each LED-chip so once you set the color you can stop talking to the strip and it will continue to PWM all the LEDs for you.

4. The SK9822 is almost a direct replacement to the APA102 and is superior in some respects, most  importantly its built-in constant-current control, If you have ever tried to power a long string of LED strips and only connect one end to the power supply, you may have noticed that the far end of the LED strip has a low voltage on its power rail due to the resistance in the long power connection. For LED strips based on APA102C and WS2812B, use dimmer voltage and red color. With SK9822, as long as the voltage remains above 3.5v, this voltage drop is unlikely to have a noticeable effect.

5. The protocol for the SK9822 is very similar to the protocol for the APA102C, but it updates the colors displayed at different times. If you replace the APA102C LED with the SK9822 LED in a low-framerate application, you may need to update the code that our APA102 Arduino library USES with the SK9822, so you can use it directly or write your own code as a reference. The color generated by SK9822 is different from the color generated by APA102C, so we do not recommend mixing APA102C and SK9822 in a single project.

Light strips advantages

   With plasticity, can be free to bend the shape — fixed in the uneven surface, easy to install (using the 3M self-adhesive) and other advantages;

   With waterproof, in case of high temperature and low temperature does not change color, low voltage long life, and other advantages;

   With bright colors and soft light (1LED lights can be composed of a loop — every 1 light can be cut to use), energy saving and environmental protection and other advantages are the ideal replacement of neon products (70% more energy saving than the neon), It is decorative contours. Making a variety of modeling the ideal lighting.
