- STM32
An industrial motor control system based on an STM32 microcontroller, providing precise stepper motor control and position management through Modbus RTU over RS485.
An external controller or automation system sends motion commands and reads position data over Modbus. The STM32 handles communication, motion control, position management and status monitoring in real time, with error detection and handling designed for industrial use.
