Description
These Red / Green LEDs are perfect for situations where two colors of LED are required and there is only space for a singular LED. The 3mm LED has three legs, with separate cathodes for each color, and a common anode. To use this 3mm White LED you will need a current limiting resistor; this will vary depending on your input voltage. Typically with a 5V supply we recommend using a 100 ohm resistor for a single LED. Alternatively you can also use a 20mA current limiter (linked below)
