We have ✅ 3 available of the AF-5880 in our Sydney warehouse. An extra 100 units available with a short lead time.

Express post delivery (2-5 business days)

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.

Key Features

  • Pre-Soldered Encoder – 24-detent rotary encoder with push-switch included and ready to use
  • Seesaw I2C Interface – Onboard microcontroller handles all encoder tracking and debouncing automatically
  • STEMMA QT / Qwiic Connectors – Solderless I2C connection with daisy-chain support
  • Built-in NeoPixel – Programmable RGB LED for customisable visual feedback, controlled over I2C
  • Interrupt Pin – Configurable INT output pulses low on rotation or button press
  • 3V & 5V Compatible – Works with both 3.3V and 5V power and logic levels
  • Status LEDs – Green power LED and red INT LED for easy monitoring
  • Breadboard-Friendly – Six 0.1"-spaced breakout pads for traditional wiring

Ideal For

  • Menu navigation, volume control, and parameter adjustment interfaces
  • Quick prototyping — encoder is pre-soldered and ready to use out of the box
  • Arduino, Raspberry Pi, and CircuitPython projects
  • STEMMA QT / Qwiic sensor and control chains

Package Contents

  • 1× Adafruit I2C STEMMA QT Rotary Encoder Breakout with pre-soldered encoder
Tip: STEMMA QT cable is not included. Connect with any STEMMA QT / Qwiic compatible cable for a solderless setup.
