I am using a Common Anode RGB LED in my project(datasheet is given below) and the different specifications for each LEDs are giving me headache. In my schematics, as shown below, I have used individual current limiting resistors valued at 150ohm. The common anode is tied to the 3.3V source. The LEDs are driven by an NPN and the switching is controlled by an MCU.
- The RED and BLUE LED have max VF=2.4V and 3.15V, which is smaller than the source 3.3V
