The Scroll Unit is a rotary encoder expansion module designed as a scroll wheel. It combines a 12-pulse through-shaft encoder, a button input, and a WS2812C programmable RGB LED.

The built-in STM32F030 microcontroller handles encoder pulse signal acquisition with integrated firmware, allowing you to easily access encoder values through I2C read operations, making the process much simpler. This unit is perfect for projects such as adjusting scale values or controlling volume.

Features

  • Based on STM32 microcontroller
  • AB phase output (12 pulses per revolution)
  • Built-in button
  • Multi-color WS2812C RGB LED indicator
