Description
Grove – RGB LED Ring (16-WS2813 Mini) is a cost-effective full color LED ring with 16 chainable and programmable WS2813 mini LEDs.
Features
- Full color RGB: 16777216 colors, 256 levels of brightness, 16 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 just plug your LED ring into Seeedunio or Arduino+BaseShild via Grove Cable, with no soldering, and no complicated wiring.
Description
The Grove – RGB LED Ring (16 – WS2813 Mini) 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 constrant 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 build-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.
When multiple light rings are connected together, the control signal can be input from the Grove SIG pin or from the DIN input. However, Grove VCC has an insufficient power supply and needs to input power from VIN.
On top of that, with the onboard Grove connector and cable, all these wonderful things only need to be plugged and unplugged.
We’ve already released the Grove – RGB LED Ring (20 – WS2813 Mini), and now the Grove – RGB LED Ring family has welcomed three new members:
- Grove – RGB LED Ring (16-WS2813 Mini)
- Grove – RGB LED Ring (24-WS2813 Mini)
- Grove – Ultimate RGB LED Ring

Hardware Overview
Note
1- Actually, the control data signal inputs are connected. So please do not input different signals at the same time.
2- The two power ports are isolated, and the Grove VCC can only supply up to 400mA, so please use VIN when multiple LED rings are cascaded.
