Encoder Unit photo

Unit Encoder is an I2C communication interface rotary encoder expansion unit. It integrates a 30-position pulse encoding knob (with button input) + 2x SK6812 programmable RGB LEDs. The built-in STM32F030 main control integrates encoder pulse signal acquisition firmware, allowing users to directly obtain the encoding value through I2C read operations, simplifying the process. It is suitable for scenarios such as scale value control/volume adjustment. Features 30-position pulse encoding knob… (M5Stack U135)
