Scroll Unit with Hollow Shaft Encoder (EC10E1220501)

Description Scroll unit is a rotary encoder expansion unit in the form of a scroll wheel. It integrates a 12-pulse through-shaft encoder + button input + WS2812C programmable RGB LED. The built-in STM32F030 microcontroller integrates encoder pulse signal acquisition firmware, allowing users to directly obtain encoder values through I2C reading operations, simplifying complex processes. It is suitable for control scenarios such as scale value control and volume adjustment. Product Features Based on STM32 microcontroller AB phase output (12 pulses per revolution) Built-in button Multi-color WS2812C RGB LED indicator I2C communication interface Includes 1x Scroll Unit 1x HY2.0-4P Grove cable (20cm) Applications Industrial Automation Smart Home Robotics Human-Computer 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/revolution RGB LED 1x WS2812C Button 1x Button I2C Communication Address 0x40 Operating Temperature 0-40°C Product Size 32*24*18.9mm Package Size 136*92*20mm Product Weight 7.3g Package Weight 12.7g LEARN AND DOCUMENTS DOCUMENTS
