M5Stack U198 Unit Step16 Encoder is a 16-position rotary encoder control unit based on an STM32G031G8U6 microcontroller. This encoder collects the BCD value of the rotary encoder in real time and visualizes the 0–F hexadecimal value via the on-board 7-segment display. The Unit Step16 encoder provides reliable physical interaction and instant visual feedback with its concise and efficient design. This device configures the rotation increment direction, display operating mode, RGB LED color, and I2C address. The Unit Step16 encode is ideal for smart interactive devices (e.g. smart-home control panels), control interfaces (e.g. volume knobs) and STEAM education hardware prototyping, and teaching.
