Description
Description Unit Step16 is a 16-position rotary encoder control unit based on the STM32G031G8U6 microcontroller. Its core function is to acquire the BCD value of the rotary encoder in real time and visualize the 0–F hex value through the integrated 7-segment display. The device communicates via an I2C interface and supports configuration of the rotation increment direction, display operating mode, RGB LED color, and I2C address, allowing multiple encoder units to be used on the same bus. Featuring a clean and efficient design, it provides effective physical interaction control and real-time visual feedback, making it ideal for smart interactive devices (e.g. smart-home control panels), control interfaces (e.g. volume adjustment, RGB lighting control, motor speed regulation) and STEAM education hardware prototyping and teaching. Features 16-position BCD rotary encoder Integrated numeric display for encoder value Adjustable display brightness and operating mode Configurable clockwise / counter-clockwise direction Programmable RGB LED color / brightness I2C communication with configurable address Development Platform UiFlow1 UiFlow2 Arduino IDE Includes 1 x Unit Step16 1 x HY2.0-4P Grove Cable (20cm) Applications Smart interactive devices (e.g. smart-home control panels) Control interfaces (e.g. volume adjustment, RGB LED lighting control, motor speed regulation) STEAM education Specifications Specification Parameter MCU STM32G031G8U6, 32-bit ARM Cortex-M0+, 64 MHz Step Encoder 16 positions, 8421 BCD code Encoder Display 7-segment display Programmable RGB 1 x WS2812 Value Update Cycle 100 ms Interface I2C @0x48, address range 0x08 ~ 0x77, data retained after power-off Standby Current DC 5 V @ 5.85 mA Operating Current Display LEDs 60%: DC 5 V @ 14.76 mA Display LEDs 100%: DC 5 V @ 24.13 mA RGB LED 100%: DC 5 V @ 18.9 mA Display LED + RGB: DC 5 V @ 29.91 mA Product Size 32.0 x 24.0 x 16.9mm Product Weight 5.5g Package Size 138.0 x 93.0 x 13.0mm Gross Weight 10.9g Rotary
