Scroll - hollow shaft encoder with push button - expansion module Unit - M5Stack U186
Scroll Unit is a rotary encoder module in the form of a roller , based on the STM32F030 microcontroller. It offers 12 pulses per revolution , a built-in button and programmable RGB WS2812C backlight. Thanks to I2C communication (address 0x40), it allows easy reading of values without complicated handling of quadrature signals. Ideal for controlling value scales, volume control or HMI interfaces in industrial automation, robotics and Smart Home applications.

Product description: Scroll - rotary encoder with push button - Unit expansion module - M5Stack U186
Scroll Unit is a control module that integrates the EC10E rotary encoder , a built-in button and a programmable WS2812C RGB diode . The encoder generates 12 pulses per revolution (AB output in quadrature), which allows precise adjustment of values such as volume, brightness or control parameters in industrial applications. Its key advantage is the use of the STM32F030 microcontroller, which supports pulse reading and transmits ready values via the I2C interface (address 0x40), eliminating the need to decode AB signals. This makes the module easy to integrate with various systems , such as Arduino IDE or M5Stack . Scroll Unit will work great in applications requiring smooth adjustment of values, such as changing parameters in automation, multimedia control, robotics or user interfaces. The module is compact ( 32 x 24 x 18.9 mm ) and easy to assemble, which makes it a versatile tool in electronic projects.
