An onboard microcontroller running Adafruit's seesaw firmware handles all pulse tracking, debouncing, and pin management — simply query the encoder values whenever you need them.\n\nDesigned in the STEMMA QT / Qwiic form factor, this breakout supports solderless I2C connections and daisy-chaining. The board accepts standard PEC11-pinout rotary encoders (not included) and features reverse-mount NeoPixels under each encoder position — visible through clear or translucent shaft encoders for colour-coded visual feedback.\n\nKey Features\n\n\n4× Encoder Positions – Read up to four rotary encoders from a single breakout board\n\nSeesaw I2C Interface – Onboard microcontroller handles all encoder tracking and debouncing\n\nSTEMMA QT / Qwiic Connectors – Solderless I2C connection with daisy-chain support\n\n4× Reverse-Mount NeoPixels – RGB LEDs visible through translucent encoder shafts, 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\nUp to 8 Boards on One Bus – Three address jumpers allow addresses 0x49 to 0x51 (up to 32 encoders total)\n\nBreadboard-Friendly – 0.1\"-spaced breakout pads for traditional wiring\n\n\nIdeal For\n\nMulti-encoder control panels and user interfaces\nAudio mixers, lighting controllers, and parameter adjustment\nArduino, Raspberry Pi, and CircuitPython projects requiring multiple rotary inputs\nSTEMMA QT / Qwiic sensor and control chains\n\n\nPackage Contents\n\n1× Adafruit I2C Quad Rotary Encoder Breakout PCB (assembled and tested)\n\n\n\nNote: Rotary encoders, header pins, and STEMMA QT cables are not included. This breakout accepts any standard PEC11-pinout rotary encoder. NeoPixels are only visible through clear or translucent encoder shafts.\n\n\nResources\n\nAdafruit I2C Rotary Encoder Guide\nArduino Seesaw Library (GitHub)\nCircuitPython Seesaw Library (GitHub)\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":1495,"title":"Default Title","sku":"AF-5752","price":14.59,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
