We've had some requests for a common Anode RGB LED, you asked, we delivered! So instead of the common pin going to ground it will go to Vcc and the signal wires go low (to ground). It seems backward to normal convention but some people like to roll that way!
This LED is bigger that the most popular 5mm LEDs but smaller than the gigantor 10mm LEDs! It gives you all of the colors in the visible spectrum in one LED, just apply 3 signals and a common positive voltage.
