Chain Encoder is a rotary encoder input node in the M5Stack Chain series. It integrates an AB rotary encoder internally, supporting rotation direction detection and pulse counting, and the center of the knob supports button input. It also integrates a programmable RGB LED for status indication and interactive display. The encoder cap features LEGO-compatible mounting holes, enabling more creative structural connections. It is suitable for applications such as human窶杜achine interaction and smart home control.
