Adafruit I2C Quad Rotary Encoder Breakout with NeoPixel

Rotary encoders offer precise control with 360-degree rotation, unlike traditional potentiometers. These innovative encoders feature tactile detents, providing satisfying feedback with every twist.

For seamless integration, this Stemma QT breakout board simplifies the process. With compatibility for up to four rotary encoders, it's perfect for creating extensive, knob-filled interfaces.

Designed for easy setup, solder any standard PEC11-pinout encoders, with or without a push-switch. The onboard microcontroller, programmed with seesaw firmware, tracks pulses and pins, saving incremental values for I2C querying.

Integration is effortless; connect using a Stemma QT cable with microcontrollers ranging from Arduino UNO to Raspberry Pi. Control and data reading are streamlined using our Arduino library, with additional support via CircuitPython/Python for Linux-based systems.

Featuring reverse-mount NeoPixels for visual feedback with translucent shaft encoders, these LEDs are controlled over I2C. The INT pin provides low pulses upon rotation or button press detection, reducing the need for constant I2C reads.

Flexibility is key, allowing up to eight encoder connections on a single I2C port through adjustable address jumpers. With connectors compatible with SparkFun Qwiic I2C, solderless connections and wide-ranging sensor chaining are supported using compatible cables.

This breakout board offers full customization, allowing for detent and detentless encoders. Note that high-speed motor encoders are not supported; it's designed for hand-rotated mechanical encoders only.

Enhance your projects with this versatile and intuitive rotary encoder breakout, providing accessible, dynamic control capabilities.
