Do you still remember we released a cool LED Ring and a LED Stick based on WS2813 Mini LEDs in the Grove ecosystem? Well…for the Seeekers who missed it, here is a recap of those modules.

Grove – RGB LED Ring (20 – WS2813 Mini)

Grove – RGB LED Stick (10 – WS2813 Mini)

Both feature 3535-sized RGB LEDs with an embedded microcontroller inside and are very fun to play with!

We believe you really enjoyed using these two modules and today we are very excited to extend our Grove – RGB LED Ring Family by introducing three new members!!!

One younger brother and two older brothers for the Grove – RGB LED Ring (20 – WS2813 Mini).

Grove – RGB LED Ring (16 – WS2813 Mini)

Grove – RGB LED Ring (24 – WS2813 Mini)

Grove – Ultimate RGB LED Ring

Let’s have a quick comparison between the members of the LED Ring family!

We used these LED Rings and made a cute little sparkling LED pig!!!! That’s right! A sparkling LED pig!!!

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.

Signal break-point continuous transmission

As long as not two or more adjacent LEDs are broken, the remaining LEDs will be able to work normally

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.

Connection Diagram of chaining the RGB LED Rings

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 insufficient power supply and needs to input power from VIN.

On top of that, with the on-board Grove connector and cable, the connection is made much easier with plug and play.
