5mm Super Bright - RGB - Common Cathode
Description / 5mm Super Bright - RGB - Common Cathode
The 5mm Red/Green/Blue (RGB) LED (Round Top, Clear) is the standard through-hole LED for Arduino/microcontroller RGB projects — mix any color with PWM control on three independent channels (red, green, blue). Clear lens with a focused 20-30 Degrees beam — bright and directional, the classic DIP LED that fits every breadboard, panel bezel, and holder on the market.
The 5mm (T-1¾) is the most popular LED size in the world — the standard for breadboard prototyping, hobby projects, panel indicators, and every electronics starter kit. Fits all 5mm holders and bezels.
Common Cathode — the shared pin connects to ground (−). Three independent color channels.

Common applications
- Arduino and microcontroller projects: The entry-point RGB LED for learning PWM color mixing. Drive each channel independently to create any color — official Arduino starter kits include this exact component.
- RGB LED cube projects: The classic "LED cube" build (4×4×4, 8×8×8) uses through-hole RGB LEDs for a 3D color display. Bulk purchase for cube builds.
- LED throwies and art: Tape to a coin cell + magnet for instant color-changing guerrilla art.
- Cosplay prop effects: Color-cycling weapon/armor accents, mood-responsive costume elements.
- Scale model accent lighting: Programmable signals, animated displays, color-coded status indicators.
Standard T-1 3/4 through-hole footprint. Fits all 5mm LED holders, bezels, and panel-mount clips. Add a current-limiting resistor matched to your supply voltage — see our LED Resistor Calculator for the exact value.
Need a wider beam? See our 5mm Diffused Round Top LEDs (soft glow, no hotspot) or 5mm Straw Hat LEDs (120–140° wide angle).
