An onboard microcontroller running Adafruit's seesaw firmware handles all pulse tracking, debouncing, and pin management — simply read encoder values over I2C.\n\nWith STEMMA QT / Qwiic connectors, you can make solderless I2C connections to any compatible microcontroller, from Arduino to Raspberry Pi. The board also features six 0.1\"-spaced breakout pads for breadboard use, and works with both 3.3V and 5V power and logic.\n\nKey Features\n\n\nPre-Soldered Encoder – 24-detent rotary encoder with push-switch included and ready to use\n\nSeesaw I2C Interface – Onboard microcontroller handles all encoder tracking and debouncing automatically\n\nSTEMMA QT / Qwiic Connectors – Solderless I2C connection with daisy-chain support\n\nBuilt-in NeoPixel – Programmable RGB LED for customisable visual feedback, controlled over I2C\n\nInterrupt Pin – Configurable INT output pulses low on rotation or button press\n\n3V & 5V Compatible – Works with both 3.3V and 5V power and logic levels\n\nStatus LEDs – Green power LED and red INT LED for easy monitoring\n\nBreadboard-Friendly – Six 0.1\"-spaced breakout pads for traditional wiring\n\n\nIdeal For\n\nMenu navigation, volume control, and parameter adjustment interfaces\nQuick prototyping — encoder is pre-soldered and ready to use out of the box\nArduino, Raspberry Pi, and CircuitPython projects\nSTEMMA QT / Qwiic sensor and control chains\n\n\nPackage Contents\n\n1× Adafruit I2C STEMMA QT Rotary Encoder Breakout with pre-soldered encoder\n\n\n\nTip: STEMMA QT cable is not included.
