Pimoroni PIM523 RGB Potentiometer Breakout Board is designed to add a colorful light-up dial and spin the Raspberry Pi project right round. This board supports the I2C interface and Nuvoton MCU that can easily incorporate a digital linear potentiometer into the project. The RGB breakout board LED can directly be controlled inside the pot as an input device that can also show a color-coded visual status. This potentiometer has a limited range of motion and is good for dials that benefit from having a set start- and end-point. The PIM523 breakout board features reverse polarity protection, RGB LED, and compatible with all models of Raspberry Pi. This RGB potentiometer breakout board is available in 25mm x 22mm x 30mm dimensions.
