  • A4988 driver board widely used in 3D printers and small CNC machines
  • Simple step and direction control interface
  • Thermal protection, over-current protection, ground fault protection
  • Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
  • Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates

1.Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
2.Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
3.Automatic current decay mode detection/selection
4.Internal UVLO
5.Mixed with slow current decay modes
6.Synchronous rectification for low power dissipation
7.Crossover-current protection
8.Thermal shutdown circuitry
9.3.3 and 5 V compatible logic supply
10.Thermal shutdown circuitry
11.Ground Fault Circuit
12.short-circuit protection
13.five optional step mode: full, 1/2, 1/4, 1/8 and 1/16
