Description
Chain Angle is a potentiometer knob input node in the M5Stack Chain series. As the potentiometer knob rotates, the voltage value at the sampling terminal varies within a fixed range. After ADC conversion by the built-in MCU, a signal value with up to 12-bit resolution is output. It also integrates a programmable RGB LED for status indication and interactive display. It is suitable for applications such as human-machine interfaces, smart home systems, and motor speed control.
Chain Angle integrates an STM32G031G8U6 core MCU and uses a UART serial cascade communication protocol. Through two HY2.0-4P expansion interfaces, more Chain series devices can be connected to build richer interactive applications.
