1. The area of ​​the board is slightly reduced. The original project PCB size is 69.723x62.357 mm, and the PCB size of this project is 42.215x70 mm.

2. The DCDC chip was replaced. The original project used MP2451 and this project uses LM2596.

3. The MOS tube package has been changed. The original project MOS tube package is 418B-02 , and this project MOS tube package is TO-252-2.

Original project description:

What can give 200% bonus to various attributes? That must be RGB!

My two favorite effects: breathing light and gradient, can be vividly displayed in RGB, so I also have a special liking for RGB, so I will also use this kind of RGB light in my home in the future, one is for lighting, and the other is for atmosphere. Through automated linkage, you can greatly enrich the colors in your home ~ RGB, which is red, green and blue, displays ever-changing colors through the blending of three colors in different proportions. RGBW has more white light than RGB, and RGBWW has more color temperature adjustment than RGBW, that is, warm and cold light. To be precise, the board I designed is called an RGB driver board. However, the RGB driver boards available on Xbao are basically three-way RGB. The most common application scenario for home lighting is still white light. RGB can pass through three channels. The color is fully brightened and white light is produced, but the brightness is not enough. W can increase the brightness by one level. WW can also adjust the color temperature under high brightness. Students who have used iPhone must know the original color display of iOS. The screen can be adjusted according to the external light. Different color temperatures allow the eyes to adapt to various environments, restore colors, and improve the reading experience; I especially like the warm feeling of warm light at home, so RGBWW is essential. In the future, I will also link it with environmental sensors to achieve The same dimming effect as the iPhone, adjusting the indoor lighting color temperature according to different lighting conditions. Of course, this five-way board is completely backwards compatible and can basically work with all light strips on the market.
