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:

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

Specifications:

1. minimum operating voltage: 8.2 V
2. maximum operating voltage: 45 V
3. continuous current per phase: 1.5 A
4. maximum current per phase: 2.2 A (with cooling)
5. minimum logic voltage: 2.5 V
6. maximum logic voltage: 5.25 V
7. dimensions: 20 x 15 mm (0.8" x 0.6 ")
