Geeetech A4988 3D Printer Stepper Motor Boards - Red (5PCS)
This product is a a4988 DMOS and Allegro micro step drive and over-current protection breakthrough in translation. The stepper motor driver£¬ the product can be in full£¬ half£¬ 1/4£¬ 1/8 and 1/16 stepper mode operation of bipolar stepper motor£¬ up to 35 V + 2 A output drive capability Translator's key to A4988's easy to implement. A step input of a micro step motor driver only needs to input a pulse. There is no sequence tables£¬ high-frequency control lines£¬ or complex interfaces. The A4988 interface is an ideal fit for application in a complex microprocessor that is not available or too heavy. Simple steps and direction control interface; The five step: different resolutions full step£¬ half step£¬ step by step£¬ eighth step£¬ sixteenth step; Adjustable current control allows you to set the maximum output current with a potentiometer£¬ which allows you to use the rated voltage of the stepper motor in order to achieve a higher rate of step voltage; Intelligent chopper control£¬ automatic selection of the correct current decay mode (fast decay or slow decay); Over temperature shutdown£¬ under voltage lockout£¬ and cross current protection
