5 PCS Allegro A4988 StepStick Stepper Motor Drivers for 3D Printer Electronics Ramps 1.4

This product is ready to use carrier board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection, fully compatible with Pololu driver board. A4988 driver board widely used in 3D printers and small CNC machines. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.

A4988 is a complete microstepping motor driver with built-in translator for easy operation. This product is available in full, half, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation. As long as the "step" input inputting one pulse drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened.
