Adafruit I2C Stemma QT Rotary Encoder Breakout with Encoder
We have ✅ 3 available of the AF-5880 in our Sydney warehouse. An extra 100 units available with a short lead time.
The Adafruit I2C STEMMA QT Rotary Encoder Breakout comes with a 24-detent rotary encoder with push-switch pre-soldered, so you can start twisting right away. An onboard microcontroller running Adafruit's seesaw firmware handles all pulse tracking, debouncing, and pin management — simply read encoder values over I2C.
With 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.
