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.
