Description
- 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
- Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects
- 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)
- MAXIMUM CURRENT =2.2AMP
