A pack of 20 common-cathode RGB LEDs in a standard 5 mm through-hole package. Each LED contains three independent colour elements — red, green, and blue — sharing a single cathode pin. Drive each colour individually for status indicators, or use PWM to mix colours and produce any hue you need.
Key Features
- Common Cathode – Single shared ground pin with independent R, G, and B anodes
- Full Colour Mixing – Combine channels with PWM to produce any colour
- Water-Clear Lens – High brightness and vivid colour output
- Standard 5 mm Package – Breadboard and perfboard compatible
- Pack of 20 – Plenty for multi-indicator or lighting projects
Specifications
- Type – 5 mm RGB LED, common cathode
- Lens – Water clear
- Forward Voltage (Red) – 1.8–2.5 V
- Forward Voltage (Green/Blue) – 2.8–4.0 V
- Typical Forward Current – 20 mA per channel
- Luminous Intensity (R/G/B) – 800 / 400 / 900 mcd
- Viewing Angle – ±60°
- Reverse Current – 10 µA (at 5 V reverse)
- Quantity – 20 per pack
Ideal For
- Multi-colour status indicators
- Arduino and microcontroller RGB lighting projects
- Mood lighting and colour-mixing experiments
- Educational electronics
Package Contents
- 20× 5 mm RGB LED (Common Cathode)
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
