M5Stack Encoder Unit

The M5Stack Unit Encoder is a rotary encoder expansion unit with an I2C interface, integrated with a 30-bit pulse encoding knob (with button function) and 2 x SK6812 programmable RGB LEDs.

The built-in STM32F030 flashed with the encoder pulse acquisition firmware, allowing users to obtain the encoded value directly via I2C. Suitable for scale value control/volume adjustment and other control scenarios.
