RGB Led Control PCA9633 (I2C)

File:TArduinoLEDPCA9633.png

Summary

RGB LED control module using the PCA9633 controller with I2C interface. Supports 4 independent PWM channels for LED brightness control, blinking, and power-saving modes.

Description

The PCA9633 is a 4-channel I2C LED driver designed for RGB or multi-channel LED applications. Each channel can be individually set with an initial value for brightness control. The driver also supports global blink functionality with configurable frequency, open-drain outputs, and a low-power sleep mode. It is well-suited for RGB LEDs, status indicators, and general-purpose LED dimming.
