[Controller & Driver] Integrated step motor controller and driver functions.It can not only realize the drive motor, but also control the working state of the stepper motor in real time[Forward & Reverse] It can not only change rotation direction by pressing button, but also by potentiometer. It is also automatically change the direction through the selected working mode to achieve multi-scene and multi-application[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[9 work states] Built-in 9 default workflow programs, covering most applications, to meet the needs of different scenarios.Forward/Reverse/Delay/Loop/Self-locking/No-lock/Rotating speed and so on[HD LCD display] The HD LCD can clearly display the speed/delay/cycle times, making it easier to browse and set various parameters. Realize high-precision control of the motor.
