A4988 Stepper Motor Driver Module

Description The A4988 is a complete micro-stepping motor driver with a built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A. 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   Packing List: 1 x Step motor driver module, pre-soldered with header pins. 1 x Heatsink   Documents: A4988 Datasheet How to control a Stepper Motor with A4988 and Arduino
