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.

Notes

1. The control data signal inputs are connected. So please do not input different signals at the same time.
2. 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.
