Diffused 5mm tri-colour LED with separate red, green and blue LED chips inside! Nice indicator, and fun to colour-swirl. 60-degree viewing angle. We like diffused RGB LEDs because they colour mix inside instead of appearing as 3 distinct LEDs.

These are Common-Anode type which means you connect one pin to 5V or so and then tie the other three legs to ground through a resistor. We carry and use CA more than CC because multi-LED driver chips (such as the TLC5940/TLC5941) are often designed exclusively for CA and can’t be used with Common-Cathode.
