Geeetech® Stepper Motor Driver A4988 With Heatsink And Sticker For 3D Printer

Description This product is a board for Allegros A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection The translator is the key to the easy implementation of the A4988 Simply inputting one pulse on the STEP input drives the motor one microstep There are no phase tables high frequency control lines or complex interfaces to program The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable oroverburdened Features 1 Simple step and direction control interface2 Five different step resolutions full step half step quarter step eighth step and sixteenth step with an output drive capacity of up to 35 V and 2 A 3 Adjustable current control lets you set the maximum current output with a potentiometer which lets you use voltages above your stepper motors rated voltage to achieve higher step rates4 Intelligent chopping control that automatically selects the correct current decay mode fast decay or slow decay 5 Over temperature thermal shutdown under voltage lockout and crossover current protection6 Short to ground and shorted load protectionPackage Included 1x A4988 stepper motor driver1x heatsink1x sticker
