• A4988 Stepper Motor Driver Carrier MUSCUILKD

Simple step and direction control interface/Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-stepAdjustable 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 ratesIntelligent 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 protectionShort-to-ground and shorted-load protection

The A4988 stepper motor driver carrier is a breakout board for Allegro's A4988 microstepping bipolar stepper motor driver. The driver features adjustable current limiting, overcurrent and overtemperature protection, and five different microstep resolutions (down to 1/16-step). It operates from 8 - 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).
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).
Note that we carry several stepper motor drivers that can be used as alternatives for this module. The Black Edition A4988 stepper motor driver carrier is available with approximately 20% better performance; except for thermal characteristics, the Black Edition and this (green) board are interchangeable. We also sell a larger version of the A4988 carrier that has reverse power protection on the main power input and built-in 5 V and 3.3 V voltage regulators that eliminate the need for separate logic and motor supplies. Our DRV8825 carrier offers approximately 50% better performance over a wider voltage range and with a few additional features, while our DRV8834 carrier works with motor supply voltages as low as 2.5 V; either of these boards can be used as a drop-in replacement for this driver in many applications.
