From the project
3W RGB LED driver board with PWM dimming for AUV image processing
A custom-designed 3W RGB LED driver board with PWM dimming capability, developed for an Autonomous Underwater Vehicle (AUV).
This board was designed to control the color output of a 3W RGB LED by adjusting each channel independently via PWM signals. The primary purpose is to support the AUV's image processing system by providing tunable, high-intensity underwater illumination.
