Pimoroni PIM522 RGB Encoder 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 rotary encoder into the project. The RGB breakout board LED can directly be controlled inside the encoder as an input device that can also show a color-coded visual status. This encoder has an unlimited range of motion and is good for dials that need to spin round continuously. The PIM522 breakout board features reverse polarity protection, RGB LED, and compatible with all models of Raspberry Pi. This RGB encoder breakout board is available in 25mm x 22mm x 28mm dimensions.
