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.)
