Smart LED WS2812B Pixel Hardware Design

About the Product

These small LEDs are not just ordinary lights – each is unique because it has a built-in small integrated circuit (IC) that is able to turn on the LED light in 16 million different colors. IC is WS2812 and it uses a single wire that can control thousands of these LEDs. With a little imagination by putting these pixels, you get superior effects with a minimum effort. These lamps are easy to control with Dasduino.

Questions

How big is the WS2812B LED Pixel PCB?

It measures 179.4 × 217 mm and has 2 copper layers, 1.6 mm thick.

What parts does the WS2812B LED Pixel use?

5,921 parts, built around the WS2812B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the WS2812B LED Pixel KiCad files?

From the SolderedElectronics/Smart-LED-WS2812B-Pixel-hardware-design repository on GitHub, at the commit this page was made from: the board is CAD/V1.0.0/PANEL/WS2812B LED Pixel.kicad_pcb and its schematic CAD/V1.0.0/WS2812B LED Pixel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the WS2812B LED Pixel design in my own project?

Its repository states no licence, so its author keeps all rights: ask SolderedElectronics before reusing the design.
