42 57 Stepper Motor Driver Controller for NEMA 17 23, Integrated Stepper Driver Module with Forward Reverse Speed Control, LCD Display Motor Controller for CNC DIY Automation

[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. Parameters support memory function that will not be lost
