24-Bit WS2812 5050 RGB LED Circular Development Board

24-Bit WS2812 5050 RGB LED Circular Development Board is a high-brightness, programmable lighting module that features 24 individually addressable pixels arranged in a precise ring formation. This module integrates the legendary WS2812B driver chip directly into each 5050 RGB LED package. Consequently, you can control the entire ring using just a single digital pin from a microcontroller. Each pixel achieves 24-bit color depth, delivering over 16 million possible color combinations with smooth PWM dimming. Furthermore, the board supports daisy-chaining, allowing you to connect multiple rings together to create complex visual displays without increasing the control pin count. Therefore, this development board represents the ideal solution for hobbyists and engineers looking to add vibrant, circular lighting effects to clocks, wearables, or UI indicators.

Key Features:

• Individually Addressable: Each of the 24 LEDs operates independently, enabling complex patterns, gradients, and animations through simple software commands.
• Single-Wire Control: The board utilizes a high-speed, one-wire communication protocol, which significantly reduces the wiring complexity for your project.
• Integrated Driver: Every LED includes its own internal constant-current driver chip, ensuring consistent brightness and color even if the supply voltage fluctuates slightly.
• Chainable Design: Features both Data Input (DI) and Data Output (DO) ports, allowing you to link multiple rings in series to expand your display.
• Vibrant 24-Bit Color: Provides 8 bits of red, green, and blue data per pixel, resulting in high-fidelity color reproduction for professional-grade lighting projects.

Technical Specifications:

Pinout and Wiring:

• 5V / VCC: Connect this pin to a regulated 5 V DC power supply. However, ensure your power source can handle the peak current of ≈ 1.5 A.
• GND: Connect to the common ground of your power supply and microcontroller.
• DI (Data Input): Connect to a digital I/O pin on your microcontroller (e.g., Arduino Pin 6).
• DO (Data Output): Connect this to the DI pin of the next LED ring if you are daisy-chaining multiple modules.
• Wiring Tip: We recommend placing a 1000 μF capacitor across the power lines and a 330 Ω to 470 Ω resistor on the data line to protect the LEDs from voltage spikes.
