Each LED is addressable, providing detailed control over colours and patterns. The ring supports signal break-point continuous transmission, providing functionality even if some LEDs are damaged. It is chainable with other LED rings and supports 5V/3.3V power. The built-in Grove connector simplifies integration, making it perfect for various DIY and professional lighting projects. You can find our Grove LED ring range here Notes * The control data signal inputs are connected. So please do not input different signals at the same time. * The three power ports are isolated, and the Grove VCC can only supply up to 400mA, so please use VIN or USB-Type C when multiple LED rings are cascaded. We recommend you use a 5V/2A adapter for the USB-Type C port.
