A4988 Stepper Motor Driver Carrier - StepStick RAMPSTEP


SKU: EF03063

weight:10g

These items are soon out of stock, and will not restock after sold-out.

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.

It's 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
