5mm RGB LED Diodes Common Cathode (500pcs)

🌈 5 mm RGB LED Diodes — Common Cathode, 4-Pin

Bright 5 mm RGB LEDs with a common-cathode 4-pin layout, so each colour channel can be driven independently. Mix red, green and blue in any combination to create almost any colour, from subtle indicators to vivid accents.

✨ Key Features

• 5 mm diffused-lens RGB LED with four pins

• Common cathode — one shared negative, three separate colour anodes
• Independent red, green and blue channels for full colour mixing
• Drives directly from 5 V through series resistors (or 3.3 V logic with suitable values)
• Standard through-hole footprint for breadboards and PCBs
• Diffused lens gives an even glow and a wide viewing angle
