STEVAL-ILL009V3
Data Brief
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
light source, has a maximum forward current of
700 mA. The NTC resistor is directly assembled
on the OSTAR
module is above 10 W, the heatsink is used to
keep the temperature in range. The biggest
advantage of the OSTAR
green and blue LEDs are in the same package,
very closely assembled and therefore the color
effect is better than with three separate LEDs.
