Schrittmotor Treiber Modul auf Basis des Allegro A4988 Chip.


Einfache step/direction Ansteuerung
Betriebsarten Fullstep  Microstep (1/2, 1/4, 1/8, 1/16)
3,3V und 5V kompatibel
Strombegrenzung einstellbar bis 2A pro Phase
Ausgang bis 35V 2A
Schutz vor Übertemperatur und Kurzschluss
Pinkompatibel mit den Pololu Board

 Der A4988 kann zwar bei Strömen bis 1A ohne Kühlkörper auskommen - bei Dauerlast ist es sinnvoll ab 750mA einen Kühlkörper zu verwenden!

Description

This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; we therefore recommend careful reading of the A4988 datasheet (380k pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil (see the Power Dissipation Considerations section below for more information).

The equivalent to A4983-board but offers overcurrent protection. If the boards get too hot, they will interrupt the current until it cools a bit. If the current is too high for the heat sinking, the motors will pulse as the current is interrupted and restored.

 

Features:

 

 

  • 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
