2 in 1 :This SMC02 is Stepper motor controller + stepper motor driver, which can be directly connected to the stepper motor. Motor Type : Working for DC10-30V Two phase 4-wire 5-wire 6-wire 8-wire stepper motor 9 Working Modes: The module has built-in multiple fixed operation modes, and users can quickly select the appropriate motion trajectory to meet different application scenarios 4 Control Mode : In addition to its built-in parameters work mode,it can also control by external buttons or others driver or UART commands LCD Display: The LCD screen can clearly display the speed/delay/cycle time, control the motor with high precision, and the controller parameters support the memory function that will not be lost 2 in 1 :This SMC02 is Stepper motor controller + stepper motor driver, which can be directly connected to the stepper motor.
