A4988 Stepper Motor Driver Carrier - StepStick
[31570]
CHF 4.85

Stock: 0

This product is currently out of stock. You might want to set a notification to receive a short one-time email when the product returns to stock next time.

This is a carrier board or breakout board for Allegroís 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 on the wiki page for more information).

This board is similar to the A4983-board but offers overcurrent protection. If the boards get too hot, it will disconnect 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 motorís 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
