M5Stack Chain Encoder
M5Stack Chain Encoder is a rotary encoder input node in the M5Stack Chain series. The M5Stack Chain Encoder integrates an AB rotary encoder internally, supporting rotation direction detection, pulse counting, and a button input. The Chain Encoder 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. This M5Stack encoder is suitable for human–machine interaction and smart home control applications. The Chain Encoder integrates an STM32G031G8U6 core controller and adopts a UART serial daisy-chain communication protocol.
