LED Circle RGB 40 LED NEOPIXEL Compatible WS2812 5050 Board

LED Circle RGB 40 LED NEOPIXEL Compatible WS2812 5050 Board

The 32-Bit WS2812 5050 RGB LED Circle Board (Outer Diameter: 126 mm, Inner Diameter: 108 mm) is a precision-engineered circular lighting module featuring 32 individually addressable RGB LEDs. Each LED integrates a WS2812 driver IC within the 5050 package, enabling full pixel-level control over color and brightness. The board is designed for reliable, high-speed digital control, with advanced signal integrity features, intelligent protection circuits, and seamless cascading capabilities. Ideal for decorative lighting, wearable electronics, status indicators, and complex embedded projects, it combines high performance with cost-effective design.

#define DELAY_MS 50

void setup() {

}
