Grove RGB LED Ring (20 - WS2813 Mini) is integrated with 20 full-color RGB LEDs with 2KHz refresh frequency, and Each pixel gray levels are 256 on the stick. All the LEDs are WS2813 Mini, which is an intelligent control and highly cost-effective LED. The Grove RGB LED Ring is a mini version of the WS2813 Digital RGB LED Ring. The RGB LED Ring are 3535-sized LEDs with an embedded microcontroller inside the LED. The WS2813s are each addressable as the driver chip is located inside the LED. Each LED has a constant current drive so the color will be very consistent even if the change of voltage.
The WS2813B-Mini intelligent control LED is an upgraded version of WS2812B, the control circuit and RGB chip are integrated into a package of 3535 components. With the help of the built-in control circuit, each LED is addressable. So you can control the lighting and color of specific LED lights as you like, creating endless lighting effects. A significant advantage of WS2813B-Mini compared to traditional LED is the support for signal break-point continuous transmission. This means that even if one or two LEDs are damaged, the entire LED ring will still work properly.
Each LED is chainable and we also keep the chainable pads on the back of the LED rings, so you can cascade several LED rings to make it even cooler. Since all those Grove - RGB LED Rings are based on WS2813 Mini, you can also connect the rings of different diameters together.
Highlighted Features
- Full-color RGB: 16777216 colors, 256 levels of brightness, 20 LEDs beads operate independently
- Multi-Components combination: Built-in control circuit in a 3535 components
- Chainable: It can be cascaded with multiple LED rings
- Breakpoint Resume: In the transmission of dual-signal wires, when a LED or LED group fails, it will not cause the other LED not to light up.
- Grove Compatible: you can plug your LED ring into Seeedunio or Arduino+BaseShild via Grove Cable, with no soldering and complicated wiring.
Applications
- Guardrail tube series, point light display series, flexible/rigid strips series, module series applications.
- Lighting stage costumes, innovative gadgets, or any other electronic products.
