STEVAL-ILL009V3

Description

This board should be connected through the 30pin connector to the STEVAL-ILL009V1 control board to be able to show the light effect with the board. The OSTAR® projection module, used as light source, has a maximum forward current of 700 mA. The NTC resistor is directly assembled on the OSTAR® module. As the power of the module is above 10 W, the heatsink is used to keep the temperature in range. The biggest advantage of the OSTAR® module is that red, green and blue LEDs are in the same package, very closely assembled and therefore the color effect is better than with three separate LEDs.
