Motor driver DRV8825

Key features:

• 4-layer, improved heat dissipation, 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.
• 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.
• 45 V maximum supply voltage.
• Built-in regulator.
• Can interface directly with 3.3V and 5V systems.
• Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout.
