SML-LX0404 LED RGB Breakout Board

The LED RGB Breakout Board provides a simple interface to control four LED RGBs for a total of 12 LEDs from any MCU (including the Arduino family). It is designed to connect directly to the standard bread board with a reduced footprint. Once connected to an MCU, the MCU can provide a sink for each LED.

Hardware Features:

Stand Alone Bread Board Compatible
Four Independently controlled LED RGBs
Designed for +3.3V Control, Each LED has a pre-selected Current Resistor
Each LED is sink controlled from any MCU including Arduinos
Each LED connected to SMT pin on bottom of Board

Description

The LED RGB Breakout Board consists of four Lumex SML-LX0404SIUP LED chips. The SML-LX0404 chip is a current sink and can be connected to any MCU. The anode should be connected to +3.3V. The reason for this is the Series resistors are calculated for current limiting based on +3.3V. Changing the anode voltage to another source will change the brightness emitting from each LED. Because the SML-LX0404 chips are current sink, the user can connect to either +5V or +3.3V Arduino (or other MCUs) and control each LED.

Easily Control four LED RGBs from an Arduino

The LED RGB Breakout Board comes with example software that blinks individual LEDs from the External MCU (Such as the Arduino Mini Pro). The user can display multiple colors using each LED RGB. The MCU will provide pulse width modulated control for each LED. Changing the duty cycle of each LED changes the overall color of the LED RGB.
