Active LED Wiring

Post by bradkean » Tue Jan 09, 2018 8:37 pm

Looking at the datasheet for the OptiTrack active LEDs, it says there's a typical forward voltage of 1.45V. If I'm using a 1.5V AAA battery to power them, can I forego using a resistor? Based on what I could find, it seems like the resistor is only for when your power source is higher voltage than the LEDs forward voltage. Is this correct?

Thanks for any tips in wiring these guys up.

Brad
