توضیحات
Description: This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection by Pololu; we therefore recommend careful reading of the A4988 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.
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.
Features: Simple step and direction control interface Full-step, Half-step, Quarter-step, Eighth-step, and Sixteenth-step Adjustable current control Intelligent chopping control Over-temperature thermal shutdown Under-voltage lockout Crossover-current protection Short-to-ground and shorted-load protectio Subdivision: 1,1 / 2,1 / 4,1 / 8,1 / 16 ize: 1.5mmX2mm (for RAMPS, ultimaker or other compatible boards);
