SparkFun BOB-11722 Rotary Encoder Breakout – Illuminated (RG/RGB)
This is a clever little breakout board for both the RGB and R/G illuminated rotary encoders. On one side, it breaks out all of the RGB pins to standard, breadboard friendly, 0.1″ headers. Turn it over and it has a footprint for the R/G version! Simply solder an encoder down to the board and you’re ready to add illuminated input to your next project.
