Product Description
The Smart LED WS2812B Ring7 is a compact 23 mm round PCB with seven individually addressable WS2812B RGB LEDs, ideal for dynamic, vibrant lighting in microcontroller projects like wearables, small displays, or visual indicators. Each LED has an integrated controller, allowing the entire ring to be driven by a single digital pin on Arduino, Raspberry Pi, or similar platforms, simplifying wiring and programming.
Operating at 5 V, each LED draws ~18 mA, with a maximum current of 126 mA. The 24-bit WS2812B protocol enables over 16 million colors per pixel. Its small size and daisy-chainable design allow multiple rings to be combined for larger arrays without extra control complexity.
Perfect for status indicators, miniature displays, or creative lighting effects, the Ring7 is compatible with popular LED libraries for chasing lights, fades, and reactive animations. Its compact, robust design makes it a versatile choice for hobbyists and professionals alike.
