● Matches 57 two-phase stepper series and below, drives 2 motors at the same time, the motor parameters do not need to be consistent
● The interface is 3.8V-24Vdc, no current limiting resistor is required
● With overcurrent, overvoltage, undercurrent and undervoltage protection functions
● The speed and motor current can be adjusted by dialing the code
● Can be connected to 10-20K potentiometer for speed adjustment
