This integrated stepper motor driver and controller combines motor drive and real-time control in one unit. It allows you to not only operate the motor but also monitor and adjust its working state. <br><br> <b>Forward & Reverse Control:</b> Easily change the rotation direction via a button or a potentiometer. The device can also automatically switch direction based on the selected working mode, making it suitable for diverse applications and scenarios.<br><br> <b>4 Control Modes:</b> In addition to the built-in parameter-based work mode, you can control the motor using external buttons, other drivers, or UART commands.<br><br> <b>9 Work States:</b> Nine pre-installed workflow programs cover most common applications, including forward, reverse, delay, loop, self-locking, no-lock, and variable rotational speed. This versatility meets various scenario needs.<br><br> <b>HD LCD Display:</b> The high-definition screen clearly shows speed, delay, and cycle times, making it easy to browse and adjust parameters. It enables precise motor control, and all settings are saved with memory function (no data loss).<br><br> <b>Specifications:</b> Material: ABS. Dimensions: 79 x 43 x 41 mm.
