RGB Full Color LED SMD Module (4-Pin, Common Cathode)–NA

Description

About this item:

• Functionality: This module is designed to achieve full-color mixing by independently controlling the intensity of its Red (R), Green (G), and Blue (B) LED elements.
• Interface: It is designed for easy interfacing with popular microcontrollers such as Arduino, ESP32, or Raspberry Pi.
• Pin Configuration (Common Cathode):
  • GND (-): This is the common cathode pin, serving as the shared ground connection for all three internal LEDs (Red, Green, and Blue).
  • R: This pin controls the Red LED. Pulse Width Modulation (PWM) is recommended for precise brightness control of the red component, allowing for a wide range of red intensities.
  • G: This pin controls the Green LED, allowing for adjustment of the green light intensity.
  • B: This pin controls the Blue LED, enabling the adjustment of the blue light intensity.
• Color Mixing: By varying the brightness of each individual Red, Green, and Blue LED via PWM (or direct voltage for on/off control), a vast array of colors can be created through additive color mixing.
