A4988 Stepper Motor Driver Module + Heat Sink for 3D Printer Reprap

This DRV8825 stepper motor driver module is an upgraded version of A4988 simple step and direction control interface, it is an upgraded version of A4988, 4-layer PCB to improve heat dissipation and reduce chip resistance The adjustable current control allows you to set the maximum current output using a potentiometer, this allows you to use a voltage higher than the rated voltage of the stepper motor for higher step rates, it uses 8.2 - 45 V and can provide up to 1.5 No heatsink or forced airflow (rated up to 2.2 per volume for adequate additional cooling) Stepper motor driver (soldering head pin soldering) is a breakout board for DRV8825 microstep bipolar stepper motor driver, intelligent chopper control automatically selects the correct current decay mode (fast decay or slow decay), built-in voltage regulator (requires any external logic supply voltage) The module has pinouts that can be used as a better performing drop-down menu board replacement in many applications, operates from 8.2V to 45V, and can deliver up to approximately 1.5A per phase. It comes with a 0.1"-pitch male pin mount DRV8825 features adjustable current limit, over-current and over-temperature protection, six micro resolutions (1/32 step down), six different step resolutions: full step, half step, 1/4 step, 1/8 step, 1/16 step and 1/32 step
