## Description

This STEMMA QT adapter makes the ANO rotary navigation encoder easy to use over I2C — no GPIO-heavy wiring needed. An on-board microcontroller running Adafruit's seesaw firmware tracks all rotary pulses and button presses, saving incremental values for querying at any time over I2C. Just plug in a STEMMA QT cable and start reading rotation and button data from any microcontroller. The adapter supports 3–5V power and logic, and features an interrupt pin that pulses low when rotation or button presses are detected, so you don't need to continuously poll the I2C bus. Four solder jumpers allow address configuration for up to 16 adapters on a single I2C bus, with additional addresses settable via EEPROM. Key Features Seesaw I2C Firmware – Handles all encoder tracking and button debouncing on-chip STEMMA QT / Qwiic Connectors – Solderless I2C connection Interrupt Pin – Configurable low pulse on rotation or button press Configurable Address – 4 solder jumpers for up to 16 on one I2C bus, plus EEPROM for extended addressing Wide Voltage Range – 3–5V power and logic Breadboard Pads – Six 0.1"-spaced breakout pads for optional breadboard use Library Support – Arduino and CircuitPython/Python seesaw libraries Also Available ANO Rotary Encoder Breakout PCB – Simple GPIO breakout without I2C Ideal For Custom navigation interfaces with minimal wiring Menu and settings controls Audio volume and media controls Projects with limited GPIO availability Package Contents 1× Adafruit ANO Rotary Navigation Encoder to I2C STEMMA QT Adapter (assembled and programmed) Important: This is just the I2C adapter PCB — the ANO rotary navigation encoder is not included and must be purchased separately. Some soldering is required to attach the encoder to the adapter.
