Tool/software:
What is the function of the 1 ohm resistor (R1 to R9) in series with the LEDs as shown in the EVM schematic.
How the value is selected for the resistor to be 1 ohm.
Is it to share the heat dissipation load with the LED driver? If so then at 20mA current rating the voltage across this resistor is 20mV only. And the dissipated power is 0.4mW.
