This low cost microstepping driver is based on the high-efficiency TB67S109AFTG IC, the maximum output current is 4.0A with 8 current options, and the microstep resolution can reach 32 (6400 steps/rev). It can take a maximum motor drive voltage of around 42V. All inputs are optically isolated giving further protection in isolating driver from control electronics and helps with noise immunity.
Note: Set the ouput current to match the rated phase current of the stepper motor before turn on the power.
