Bi-color LED

Description

A red and green LED emitter in a single package. Both controlled independently. Can use PWM on each LED to mix yellow-orange colors.

Also called: two color LED, red/green LED, mini two color, dual light LED, KY011 (5mm), KY029(3mm).

Only difference between the two versions of the board pictured above is the LED size.

Found in kits: 37 sensors, 45 sensors.

Specification/Notes:

• Voltage: 3.3V to 5.0V
• Current: under 20mA typical per LED
• LED sizes: 3mm, 5mm
• Size: 20mm X 60mm

Some modules have current limiting resistors, some do not. The typical resistance value is 120 – 330 Ohms. The LED color pair is usually red/green, but sometimes yellow/green. The two LED dice internal to the package are common cathode.

There are a number of different sources for these modules. Not every module that looks similar to the ones here behaves exactly the same. Check the specific module that you have for differences in function, voltage levels, pinout, and inactive/active states. Some modules have been found to have incorrectly labeled pins and even poorly soldered components.

Module Pin-out:
