Description
The DRV8825 stepper motor driver module is a breakout board for Texas Instrument's DRV8825 microstepping bipolar stepper motor driver.
The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver modules, so it can be used as a higher-performance drop-in replacement for those boards in many applications. The DRV8825 features adjustable current limiting, overcurrent, and overtemperature protection, and six microstep resolutions (up to 1/32-step). It operates from 8.2 V to 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:
- 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
- Can interface directly with 3.3 V and 5 V systems
- 5A maximum drive current
- Up to 1/32 microstepping
- 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
- Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects.
- 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)
- 2V to 45 V maximum supply voltage
- Built-in regulator (no external logic voltage supply needed)
Package Includes:
