Grove - RGB LED Ring board (20 - WS2813 Mini) which is a cost-effective full colour LED ring with 20 chainable and programmable WS2813 mini LEDs. It is integrated with 20 full-colour RGB LEDs with 2KHz refresh frequency, and each pixel grey levels are 256 on the stick. All the LEDs are WS2813 Mini, which is an intelligent control and high 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 constraint current drive so the colour will be very consistent even if the change of voltage.

• 16777216 colours, 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: transmission of dual-signal wire, LED/LED group fail, LEDs will continue to light
• Plug LED ring into Seeeduino or Arduino+BaseShield via Grove cable, w/ no soldering, complex wiring
• 3.3V/5V power
• 0.7mA/LED quiescent current
• 16mA/LED RGB channel constant current
• 2KHz fresh frequency and reset time >280μs
• Operating temperature range from -25 to 85°C
