POLULU STEPSTICS A4988 IN INDIA

Stepstick A4988 is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection. This stepper motor driver lets you control one  bipolar stepper motor  at up to 2 A output current per coil. Here are some of the driver’s key features: Simple step and direction control interface Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step Adjustable 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 rates Intelligent 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 protection Short-to-ground and shorted-load protection  Specifications: Minimum operating voltage:            8 V Maximum operating voltage:         35 V Continuous current per phase:      1 A2 Maximum current per phase:        2 A3 Minimum logic voltage:                3 V Maximum logic voltage:               5.5 V Microstep resolutions:       full, 1/2, 1/4, 1/8, and 1/16
