About this product
*A4988 stepstick stepper motor driver five-step resolution: there are 5-steps resolution of the stepper motor drive modules, such as full-step, half-step, quarter-step, eight-step, sixteen-step, and the output drive capacity is up to 35V and -2A~2A
*This A4988 stepper motor driver lets you to operate bipolar stepper motors in full, half, quarter, eighth,and sixteenth-step modes, with an output drive capacity of up to 35 V and 2 A.
*The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened, the translator is the key to the easy implementation of the A4988. Simply inputting one pulse on the STEP input drives the motor one microstep.
*The A4988 stepper motor drive modules can provide thermal shutdown protection, over current protection, ground fault protection and crossing current protection
*The A4988 stepper motor drive module is compatible with stepper motor/ 3D printer/ CNC/ engraving machine/ supported 3D printer and more; Please confirm whether the product model is suitable before buying
Description
 Simple step and direction control interface
 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
 3.3 and 5 V compatible logic supply 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
 Short-to-ground and shorted-load protection
 Thermal shutdown circuitry
 Ground fault protection
 Load short-circuit protection
 Low RDS (On) output
 Automatic current decay mode detection / selection
 Mix with slow current decay modes
 Synchronous rectification for low power dissipation
 Cross-current protection
 Optional step five modes: full, 1/2, 1/4, 1/8 and 1/16
 Package included:
 8 x A4988 stepstick stepper motor driver module (with PINs)
 8 x Heatsink
 Note:
 Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver.
 (More generally, rewiring anything while it is powered is asking for trouble.)
