This product is a breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection;
OOTDTYThis 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 translator is the key to the easy implementation of the A4988.
Simply inputting one pulse on the STEP input drives the motor one microstep.
There are no phase sequence tables, high frequency control lines, or complex interfaces to program.
The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.
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
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
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.)
