Adafruit I2C Stemma QT Rotary Encoder Breakout with Encoder

Enjoy seamless integration and enhanced functionality with this versatile rotary encoder Stemma QT breakout. Unlike traditional potentiometers, it features 360-degree rotation with tactile feedback through detents.

This breakthrough device simplifies what was once a complex task with its onboard microcontroller, preloaded with seesaw firmware, managing timers, interrupts, and debouncing. It tracks all pulses and pins, storing incremental values accessible anytime via I2C.

Simply plug in using a Stemma QT cable to connect with any microcontroller, from Arduino UNO to Raspberry Pi. The pre-soldered encoder provides immediate use, though a compatible knob can be added for customization.

Employ our Arduino library or CircuitPython/Python code to control and read data efficiently. Easily add to a breadboard using six 0.1"-spaced breakout pads, waterproofed with 3 to 5V DC power, and 3 or 5V logic I2C data.

Enhance user interaction utilizing the configurable INT pin for detecting rotation or push-button events and experience a vivid color feedback with the onboard NeoPixel, all over I2C.

Expand your projects by connecting up to 8 encoders on a single I2C port, configurable through onboard address jumpers. Compactly designed at 1" x 1", the PCB ensures maximum utility without wasting space.

The kit includes an assembled PCB breakout with a rotary encoder, seesaw chip circuitry, and a small header. The STEMMA QT connectors are compatible with SparkFun Qwiic I2C connectors, facilitating solderless connections.
