Description

Unit Scroll is a wheel-shaped rotary encoder expansion unit. It integrates a 12-bit pulse through-shaft encoder, button input, and a WS2812C programmable RGB LED. The built-in STM32F030 controller includes firmware for encoder pulse signal acquisition, allowing users to directly obtain encoder values through I2C, greatly simplifying the operation process. This unit is suitable for control scenarios such as scale value control and volume adjustment.

Features

• Based on STM32 microcontroller
• AB phase output (12 pulses/rotation)
• Built-in button
• Multi-color WS2812C RGB LED indicator
• I2C communication interface

Includes

• 1 x Unit Scroll
• 1 x HY2.0-4P Grove cable (20cm)

Applications

• Industrial automation
• Smart home
• Robotics
• Human-machine interaction
