The LED Driver 3 Click Board™ is an RGB LED driver, capable of driving RGB LEDs with up to 30mA per segment, via the digital I2C interface. It comes with an RGB LED on-board, and is capable of displaying a palette of 32768 colours. It features an integrated circuit with three independent LED driver sections and a programmable gradual dimming control, which gives a smooth dimming effect. Heat dissipation is taken to the minimum, due to a fact that the used driver IC works with up to 94% efficiency.
