Feature:


 


This product is a carrier board or breakout board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; here are some of the driver's key features:


+ Simple step and direction control interface


+ 5 different step resolutions: full-step, 1/2-step, 1/4-step, 1/8-step, and 1/16-step


+ 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


+ 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


 


Using the driver:


 


POWER connections: The driver requires a logic supply voltage (3 5.5 V) to be connected across the VDD and GND pins and a motor supply voltage (8 35 V) to be connected across VMOT and GND. It can deliver up to appr. 1 A per phase without a heat sink or forced air flow.


 


MOTOR connections: 4, 6, and 8-wire stepper motors can be driven by the A4988 if they are properly connected.


 


  Low RDS (On) Output


· Automatic current decay mode detection / selection


· Mix with slow current decay modes


· Synchronous rectification for low power dissipation


· Internal UVLO


· Cross-current protection


· 3.3 and 5 V compatible logic supply


· Thermal shutdown circuitry


· Ground fault protection


· Load short-circuit protection


· Optional step five modes: full, 1/2, 1/4, 1/8 and 1/16
