HALJIA 3D Printer A4988 Stepstick Reprap Stepper Motor Driver Module With Heat Sink Compatible with Arduino

Simple step and direction control interface, Short-to-ground and shorted-load protection Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step 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 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 Product description 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 ¡À 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
