Hyuduo WS2812B Ring - 3.3 Inches Diameter

[Ultra Bright 24-Bit LEDs] Features 24 individually addressable RGB LEDs with 5050 chips for vibrant colors and consistent brightness at 5V. [Easy Daisy-Chaining] Connect multiple rings via a single data line, ideal for expanding lighting projects without complex wiring. [Microcontroller Compatibility] Works seamlessly with and other real-time microcontrollers using WS2812B protocol. [Compact & Lightweight] 3.3 inches outer diameter and 8g weight for flexible integration into decor or wearable projects. [Plug-and-Play Design] Includes pre-assembled ring with no external resistors needed, for immediate use with provided libraries. Features: Round and round and round they go! 24 ultra bright smart LED are arranged in a circle with 3.3" (85mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one micro-controller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you're to rock. There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time micro-controller such as an AVR, PIC, mbed, etc. It cannot be used with a -based microcomputer or interpreted micro-controller. Our wonderfully-written library supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please around. An 8MHz or processor is required. Comes as a single ring with 24 individually addressable RGB LEDs assembled and tested. Specifications: Voltage: 5V DC LED: 24-bit Inner Diameter:
