# SparkFun Qwiic Twist RGB Rotary Encoder

> SparkFun DEV-15083 Qwiic Twist: an I2C rotary encoder breakout — Bourns PEL12T illuminated 24-detent encoder with push button and RGB LED (16 M colours, PWM), read by an on-board ATtiny84 that counts ticks and direction and reports them over I2C (0x3F default, 0x3E jumper, software-configurable, up to 111 on one bus), interrupt output, 3.3 V, ~2.8 mA (LEDs off) to 40.6 mA, 25.4 × 30.5 mm, 25 mm tall.
