5pcs A4988 Stepstick Stepper Motor Driver Module with Heat Sink for 3D Printer Reprap

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

Fetures:
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 toachieve higher step rates
