M5Stack Chain Angle (STM32G031) Wireless or rotary-axis modules for labThe Chain Angle is a potentiometerbased input node in the M5Stack Chain series. As the knob rotates, the samplingterminal voltage changes within a defined range. The builtin MCU performs ADC conversion and outputs a signal with up to 12bit resolution. A programmable RGB LED is integrated for status indication and interactive visual feedback, making the module ideal for humanmachine interfaces, smart home systems, and motor speed control. Core &
