Description
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 Specifications Specification Parameter MCU STM32F030F4P6@32-bit ARM Cortex-M0 processor Rotary Encoder EC10E Rotary Encoder Output AB two-phase quadrature output Rotary Encoder Pulses 12 pulses/rotation RGB LED 1x WS2812C Button 1x button I2C Communication Address 0x40 Operating Temperature 0 ~ 40°C Product Size 32.0 x 24.0 x 18.9mm Product Weight 7.5g Package Size 138.0 x 93.0 x 19.9mm Gross Weight 12.7g Product Comparison Product Compare Unit Scroll Unit Encoder Unit 8Encoder Form Wheel Knob Knob Channels 1 1 8 Resolution 12 pulses/rotation 30 pulses/rotation 15 pulses/rotation Position AB Quadrature Output AB Quadrature Output AB Quadrature Output Communication Mode I2C (0x40) I2C (0x40) I2C (0x41) Learn and Documents → DOCUMENTS
