Ever hear of a thing called RGB? Red, Green, Blue? How about an RGB LED? These 5mm units have four pins: one for each color and a common anode. Use this one LED for three status indicators or pulse width modulate all three and get mixed colors! **Note:** The datasheet below is for the common cathode version of these LEDs, all of the values are the same except that instead of sharing a cathode, these share an anode. An updated datasheet will be added as soon as possible. **** * Forward Voltage (RGB): (2.0, 3.2, 3.2)V * Luminosity (RGB): (800, 4000, 900)mcd **** * [Datasheet](http://cdn.sparkfun.com/datasheets/Components/LED/YSL-R596AR3G4B5C-C10.pdf) * [LED Tutorial](https://learn.sparkfun.com/tutorials/light-emitting-diodes-leds)
