Features:
Driver capability up to 1.2A (RMS) continuous coil current.
Supports Step/DIR interface & SPI interface two control modes. Combined maximum efficiency & optimum motor torque operation without noise.
Reduce energy consumption by 75%. Thermal protection, over-current protection, & ground fault protection.
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motors rated voltage to achieve higher step rates.
