LED RGB 5mm 4 Pins CC (1pcs)

The LED RGB 5mm 4 Pins CC is a 5 mm round through-hole LED that holds red, green and blue chips in one package with a shared common cathode (CC). Drive each colour pin on its own, or mix them with PWM, to create almost any colour from a single LED. It is sold as a single piece and is a favourite in Arduino and ESP32 lessons on colour mixing.

LED RGB 5mm 4 Pins CC Specifications

• Type: RGB LED, common cathode
• Size: 5 mm round
• Pins: 4 (red, green, blue and the common cathode); the longest leg is the common cathode
• Typical current: up to 20 mA per colour
• Typical forward voltage: about 2 V for red, about 3 V for green and blue
• Mounting: through-hole, breadboard friendly
• Pack size: 1 piece

LED RGB 5mm 4 Pins CC Applications

• Colour mixing projects with Arduino and ESP32 PWM pins
• Status indicators that change colour
• Mood lights, night lights and decorative lamps
• STEM lessons on PWM, light and colour

What's in the Box

• 1 × 5 mm RGB LED, common cathode

Tip: Connect the longest leg to GND and use a separate resistor of about 220 Ω to 330 Ω on each colour pin at 5 V. Writing a higher PWM value to a pin makes that colour brighter, so you can blend red, green and blue in any ratio.
