FIT0676 93 LEDs WS2812B RGB 6 Ring Lamp

Introduction

This WS2812B ring lamp is composed of 93 lamp beads in 6 circles. The 6 rings in the lamp panel can be controlled individually, and cascade control is supported for each ring. You can join all rings together by connecting the DI of the second circle to the DO position of the first circle, and so on. Each LED is an individual pixel point that consists of three primary colors: red, green and blue. It is able to achieve 256 levels of brightness display and 16777216 full color display, and the scanning frequency is no less than 400Hz/s.
