The DRV8825 Stepper Motor Driver with Aluminum Heat Sink is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver.
The module has a pinout and interface that are nearly identical to those of the stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.
The features adjustable current limiting, overcurrent, and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).
Features of DRV8825 :
- Microstep resolutions: full, 1/2, 1/4, 1/8, 1/16, and 1/32.
- 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. Hence 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)
- 45 V 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
