HW-479 RGB LED Module

HW-479 RGB LED Module

The HW-479 RGB LED Module is a compact and efficient solution for adding colorful lighting effects to your electronic projects. Featuring a 5mm common cathode RGB LED and integrated current-limiting resistors, this module allows for smooth color transitions and brightness control via PWM signals. Its straightforward design and compatibility with various microcontrollers make it an excellent choice for both beginners and experienced developers.

The LED is a common cathode type which means all 3 of the LEDs have their cathodes tied together.  The cathode is connected to the ground and the red, green, and blue LED pins should be connected to digital or PWM output pins. The module has built-in 150 ohm series resistors to limit currents to a safe level, so no additional current-limiting resistors are required. The LED housing is clear, so the LED output is quite bright when viewed straight on unless PWM is used to lower the brightness.

Features:

• 5mm common cathode RGB LED
• Integrated 150Ω resistors for each color channel
• Supports PWM control for color mixing and brightness adjustment
• Compatible with Arduino, Raspberry Pi, and other microcontrollers
• Compact size for easy integration into various projects
