M5Stack Scroll Unit with Hollow Shaft Encoder (EC10E1220501)

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. Features: Based on STM32 microcontroller AB phase output (12 pulses per revolution) Built-in button Multi-color WS2812C RGB LED indicator I2C communication interface Rotary Encoder : EC10E Rotary Encoder Output : AB two-phase quadrature output Rotary Encoder Pulses : 12 pulses/revolution RGB LED : 1x WS2812C I2C Communication Address : 0x40 Applications: Industrial Automation Smart Home Robotics Human-Computer Interaction Package Includes: 1 x Scroll Unit 1 x HY2.0-4P Grove cable (20cm)
