DRV8825 microstepping bipolar stepper motor driver.
This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil
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 step rates
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
45V maximum supply voltage
Built-in regulator (no external logic voltage supply needed)
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
4-layer, 2 oz copper PCB for improved heat dissipation
Exposed solderable ground pad below the driver IC on the bottom of the PCB
Adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step).
It operates from 8.2V to 45V and can deliver up to approximately 1.5A per phase without a heat sink or forced air flow (rated for up to 2.2A per coil with sufficient additional cooling)
