Various functions: The stepper motor controller can adjust the angle, speed, direction and delay time of the motor. The micro-stepping resolution can reach 1/128, allowing you to control the motor more accurately.<br> 9 operating states: The stepper motor controller has built-in 9 fixed operating modes, including forward rotation, reverse rotation, delay, cycle, etc., which can select the operating mode faster. In addition to the built-in parameter working mode, you can also control it through external buttons or other drives.<br> [High-definition LCD display] The stepper motor controller is equipped with a high-definition LCD display, which can easily read parameters and set parameters more accurately. The module also has a power failure memory function to prevent your parameters from being lost.<br> Forward and Reverse Rotation: The stepper motor controller can change the direction of motor rotation by pressing a button, and you can also choose to use a range of working modes to choose two modes, automatic or manual.<br> 13 menu setting functions: stepper motor controller includes cycle number, motor turn, delay time, number of pulses, forward speed, flip speed, etc. External buttons and rotary encoders make setting parameters very simple.<br> color:Photo color<br> Material:plastic<br> Package Contents:<br> 1 x controller<br> 1 x plug wire<br> Only the above package content, other are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
