KY-009 5050 Full-Colour RGB SMD LED Module, 5V

The KY-009 RGB SMD LED Module features an onboard 5050 full-colour LED designed for creative lighting and visual indicator projects. By supplying PWM signals to the individual red, green, and blue pins, students and makers can mix colours to generate custom lighting effects. It operates at 5V and connects straightforwardly to Arduino and a variety of microcontrollers.

Full-colour light mixing

The module is fitted with a 5050 full-colour SMD LED that delivers rich colour blending. Adjusting the PWM input voltage across the red, green, and blue pins controls the strength of each primary colour to achieve a complete colour-mixing effect.

Onboard current limiting

Equipped with built-in tricolour limiting resistors, the board protects the LED elements against excessive current and burn-out. It operates on a 5V supply voltage using a common cathode drive configuration.

Microcontroller compatibility

This module interfaces smoothly with Arduino and a variety of other microcontrollers. It provides an accessible way for hobbyists and learners to experiment with PWM signals and programmable lighting.
