HW-479 RGB LED Module

The HW‑479 RGB LED Module is a compact, full‑color lighting module that combines red, green, and blue LEDs into a single unit. It features a 5 mm common cathode RGB LED with integrated current‑limiting resistors on each color channel, making it easy to use without adding external resistors. By controlling the red, green, and blue channels using PWM (pulse‑width modulation) signals from a microcontroller like an Arduino or Raspberry Pi, you can mix a wide range of colors and adjust brightness for dynamic lighting effects. Its small size and simple four‑pin interface (R, G, B, GND) make it ideal for DIY electronics, education, prototypes, mood lighting, and interactive projects.
