Mini Stepper Motor Control Board Module Servo Motor Controller 3.5V-12V ESC Driver for RC Robot Car Drone

[This product drives a relatively quiet stepper motor; once adjusted, the noise is almost inaudible.] [Basic Usage Overview] 1. The default mode is cycle mode. After power-on, the motor continuously cycles. You need to change it to your desired mode. 2. How to change the mode? Purchase a USB to TTL adapter and connect the board to your computer using it (for specific TTL wiring instructions, please refer to the corresponding solder joints on the board in the link). Then, download the debugging software from the cloud drive to modify the mode. You can also adjust: speed, force, and cycle. Other Notes: 1. This module can control the stepper motor in ten modes, basically meeting the needs of various motion conditions: cycle mode, unidirectional mode, servo mode, button jogging, serial port start/stop, serial port jogging, single run, unidirectional throttle, and bidirectional throttle.
