Product Overview

This module is a mechanical rotary encoder that converts rotational displacement into digital pulse signals, supporting bidirectional counting (unlimited turns). The onboard push button allows functions like menu confirmation or reset. It uses quadrature encoding with A and B outputs 90° out of phase, making it easy to determine rotation direction and steps. The board features a PH2.0 5‑pin anti‑reverse connector, operates from 3~5V, and has a compact size with M4 screw holes compatible with LEGO mounting. Ideal for volume control, menu selection, parameter setting, and other HMI applications.
