STEPPER DRIVER BOARD

Breakout board for TI DRV8825 microstepping bipolar stepper motor driver with adjustable current limiting, over-current and over-temperature protection and 6 microstep resolutions (down to 1/32-step). It allows you to control a bipolar stepper motor in a simple way.
Features:

simple step and direction control interface
six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
current adjust trimmer
can interface directly with 3.3 V and 5 V systems
over-temperature thermal shutdown, over-current shutdown and under-voltage lockout
short-to-ground and shorted-load protection
