  • 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

Features:
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
