Keyes-style KY-011 breakout carrying a single 5 mm bi-colour LED - red and green dice inside one lens, sharing a common cathode. Drive one pin for red, the other for green, or both together for amber, and use PWM to fade between them. There are no resistors on the board, so add about 220 ohm in series per colour on 5V (120 ohm on 3.3V). A tidy one-part status light for good/bad, charging/charged or armed/idle.
Key features
- 5 mm red + green LED in one lens
- Common cathode, 3 pins: red, green, GND
- Both on together gives amber
- PWM-dimmable for colour blending
- No onboard resistors - add 220 ohm at 5V
- 150 degree viewing angle
