Applications

  • Dual-state indicator circuits
  • Arduino and Raspberry Pi projects
  • Power and warning indicators
  • Control panels and dashboards
  • Compact lighting and signal status modules
  • Consumer electronic device indicators

How to Use

  1. Identify the common cathode pin (usually the middle pin).
  2. Connect the cathode to ground (GND).
  3. Use a current-limiting resistor (330E–1K) on each anode pin.
  4. Apply voltage to the red anode to light red.
  5. Apply voltage to the yellowish-green anode to light greenish-yellow.
  6. Drive both together to generate mixed illumination.
