1 pcs : U135 - Encoders Rotary encoder expansion unit with I2C interface with 30-bit pulse encoding knob

Unit Encoder STM32F030 M5Stack Unit Encoder STM32F030 is a rotary encoder expansion unit with an I2C interface, integrated with a 30-bit pulse encoding knob (with button function) and two SK6812 programmable RGB LEDs. This unit encoder has built-in STM32F030 flashed with the encoder pulse acquisition firmware. The STM32F030 of the unit encoder allows users to obtain the encoded value directly via I2C. This unit encoder features a 30-bit pulse encoding knob (30 pulses per rotation), two SK6812 programmable RG, and one-button input. The unit encoder is ideally used in Human-Machine Interaction (HMI), volume knob and is suitable for scale value control/volume adjustment and other control scenarios.
